2026-02-18

New: Passive Income Boost Items

• Snackbar Keten (Snackbar Chain) — +500 bitterballen per seconde per stuk
• baseCost: 500K, costMultiplier: 2.5, unlocks at 100K score
• High-tier flat auto producer to bridge the gap between Factory (+100/sec) and multiplier items

2026-02-13

• Added donation banner at the top with Ko-fi and Discord buttons
• Ko-fi button in red, Discord button in brand purple

• Returning players see a dismissable toast banner when a new version is deployed
• First-time players (no stored version) see nothing

• Full i18n support (Dutch + English)
• Changelog page (changelog.html) — standalone dark-themed page with full release history
• Build script injects real version into JS constant and copies changelog to dist/

New: "Ballen Hoog Houden" Juggle Minigame

• Juggle minigame — tap bitterballen to keep them in the air before they hit the ground
• New ball spawns every 5 seconds; 3 misses = game over
• Canvas-based physics with gravity, horizontal bouncing, and rotation
• Reward: max balls in air x5 click multiplier boost for 30 seconds (applies to clicks and auto-production)
• Green-themed boost timer bar appears during boost
• Gated behind Nationale Hap level (index 3, 10M score); 25% chance in random minigame selection
• Guided tour on first play (3 steps explaining mechanics and reward)
• Two new achievements: "Jongleur" (3+ balls, blue tier) and "Cirque du Bitterbal" (5+ balls, purple tier, hidden)
• Full i18n support (Dutch + English)
• Mobile-safe: touch-action manipulation, context menu prevention, pointer events
• Devtools: "Start Juggle Minigame" button, juggle boost status in live stats

Fixed: Accidental Minigame Activation on iOS

• Rapid tapping on mobile could trigger the hold-to-play minigame because iOS fires pointerup/pointercancel with mismatched pointer IDs during fast touch sequences
• Added activePointerId tracking so only one pointer is tracked at a time; stale pointers are cleaned up instead of permanently blocking input
• Raised HOLD_THRESHOLD from 500ms to 700ms to give mobile players more room before a tap becomes a hold
• Hold timeout callback now verifies the originating pointer is still active before starting a minigame

Fixed: Bitterbal Locking Up After Catching Frikandel/Kroket on iOS

• After catching a frikandel mid-tap, the bitterbal would permanently stop responding to clicks while frikandellen still worked
• Cause: activePointerId guard was too strict — handlePointerEnd rejected events with mismatched pointer IDs, leaving the tracked pointer permanently stuck
• Fix: handlePointerEnd now unconditionally clears activePointerId; handlePointerStart cleans up stale pointers instead of rejecting new ones

Fixed: Android Long-Press Context Menu During Minigames

• Long-pressing during the cooking or mosterd minigame on Android triggered the browser's native "Save image / Share" context menu
• Added touch-action: manipulation, -webkit-touch-callout: none, and user-select: none CSS to both .cooking-minigame and .mosterd-minigame
• Added contextmenu event listeners on both minigame overlays to preventDefault()

Fixed: Cooking Minigame — Tour Starting the Fry Timer

• When the cooking minigame tour appeared for the first time, the fry timer started immediately because isHolding was still true from the bitterbal hold that triggered the minigame
• startCookingMinigame() now resets isHolding, clears holdTimeout, and removes the holding CSS class before showing the tour or starting stage 1

Fixed: Cooking Minigame — Bitterbal Interaction During Stages 2 & 3

• During the sauce and cooling stages, pointer events on the bitterbal could still fall through to doClick() or interfere with cooking state
• handlePointerEnd now returns early during any active cooking stage (not just stage 1), since all cooking stages handle their own pointer events on the cooking overlay

Changed: Autoclicker Detection — Hard CPS Cap at 25

• Autoclickers with randomized intervals could bypass the coefficient-of-variation check
• Added a hard cap: mean click interval below 40ms (25+ CPS) now triggers the autoclicker penalty immediately, regardless of variance
• Original behavioral check (low CV + high speed) still catches slower robotic clickers

2026-02-07

New: Medium Rare (Shop Item)

• Milestone item — buy once, unlocks at 75M score
• Halves the fastfood click threshold (15 → 8 clicks needed in 3s window)
• Fastfood meter fills 2x faster, making it easier to sustain and earn chests

New: Kroket Powerup

• Rare variant of frikandel — spawns 1 in 10 times instead of frikandel
• 25x multiplier during Kroket Koorts (vs frikandel's 10x), same 5-second duration
• 220px clickable powerup with golden glow, 12 animated radiating streaks
• Mini kroketten during fever are 3x larger than mini frikandellen (240px vs 80px)
• "KROKET IS GROTE BITTERBAL" marquee scrolls across the screen at 25% opacity during kroket fever
• Fever timer label switches to "KROKET KOORTS!" / "KROKET FEVER!"
• Spawnable from devtools panel ("Spawn Kroket" button)

New: Achievement — "Best Druk in je Eentje"

• 🤹 Click frikandel, refresh frituurvet, click bitterbal, and complete minigame — all within 30 seconds
• Runtime tracker (not persisted) stores timestamps of each action; checks if all 4 fit in a 30s window

New: Achievement — "Kroket is Gewoon een Grote Bitterbal"

• 🥟 Unlocks on first kroket click

New: Achievement Tier System (WoW-style Rarity)

• Achievements now have colored borders/glow based on rarity tier
• Gray (Common) — basic first-time actions (first click, first fever, etc.)
• Green (Uncommon) — moderate milestones (100 clicks, airfryer, etc.)
• Blue (Rare) — harder milestones (1k+ clicks, perfect dip, etc.)
• Purple (Epic) — difficult challenges (50k+ clicks, Hold my Biertje, Best Druk, etc.)
• Orange — extreme achievements (1M clicks, Bek Verbrand, Vette Shit)
• Legendary — Fried Mind only (ultimate achievement, extra glow)
• Applied to both achievement panel cards and share card pills

Changed: Frietpan Frank Reworked

• New buff: Frituurvet decay rate halved (0.25%/sec → oil lasts 2x longer)
• Removed: Mini Fryer 2x bonus and Airfryer 60-second penalty
• Unlock: Now requires 150k score (unlocks alongside frituurvet instead of at 1k)

Fixed: Share Score Crashing with Achievements

• btoa() threw DOMException when share payload contained emoji characters (from achievement icons)
• Replaced with UTF-8-safe b64Encode/b64Decode helpers
• Verify function has fallback for old payloads encoded with plain btoa

Changed: Share Verification Code Optional

• [BB:...] signed payload no longer included in share text by default
• Checkbox "Voeg verificatiecode toe" / "Include verification code" in share modal to opt-in
• Share card achievements now displayed centered in their own rounded box

New: Internationalization (i18n)

• Language Toggle in header — flag button (🇳🇱/🇬🇧) switches between Dutch and English
• Full English translation of all UI text: shop items, achievements, tour steps, modals, timers, celebrations, minigames
• data-i18n / data-i18n-html / data-i18n-placeholder attributes on static HTML elements
• t(key) translation function with flat key lookup (STRINGS.nl / STRINGS.en)
• getItemName() / getItemDesc() / getLevelName() helpers for array-based content
• Language preference persisted in localStorage (bitterballen_lang)
• Dutch remains the default language

Fixed: Cheat Detection False Positives (VALSSPELER)

• Root cause: Runtime delta check used current multiplier state, but buffs (fever/werpen/mustard) could expire mid-interval causing under-estimation of legitimate score
• Fix: Added resetIntegrityTracking() — resets score baseline and timestamp whenever any buff starts or ends
• Called at: fever start/end, mustard start/end, werpen buff start/end, chest completion, BekVerbrand/VetteShit unlock
• Increased headroom from 3x to 5x as additional safety margin

New: Share Score & Achievements

• Share Button in shop panel — opens share modal with visual stats card
• Stats Card — shows score, level, achievements, clicks, click power, auto power, and special badges (Bek Verbrand / Vette Shit)
• Copy to Clipboard — copies human-readable stats + signed payload [BB:<base64>] for verification
• Native Share — uses Web Share API on supported devices (mobile)
• Verify Section — paste someone's shared score to verify authenticity via FNV-1a checksum signature
• Share data is signed with the same anti-tamper checksum; tampering with the payload invalidates the signature

2026-02-06

New: Anti-Tamper System (3-Layer Protection)

• Layer 1: Save Integrity — Game saves are signed with an obfuscated FNV-1a checksum; tampering with localStorage JSON triggers penalty
• Old saves (without checksum) are migrated automatically on first load
• Layer 2: Runtime Monitoring — Periodic (every 5s) validation that score deltas are plausible given click power, auto power, active multipliers, and elapsed time
• Also validates that clickPower and autoClickPower match item-derived calculations
• 3x headroom to prevent false positives during legitimate extreme play (fever + werpen + vetteShit = 500x)
• Layer 3: State Integrity — Periodic checks that state object properties haven't been replaced with getters/setters via Object.defineProperty
• Penalty: VALSSPELER! — On tamper detection: full-screen red overlay with "VALSSPELER!" text, save wiped, game blocked for 1 minute (persists across reload)
• Dev mode (devtools.js loaded) bypasses all anti-cheat checks

Fixed: Mobile Double-Tap Zoom

• Added touch-action: manipulation to body — prevents double-tap zoom while preserving pan and pinch-zoom

Changed: Autoclicker Detection Sensitivity

• Reduced sensitivity: raised max CV threshold from 0.12 to 0.18 and minimum clicks from 30 to 40

New: Bek Verbrand (4th Star Ultimate Tier)

• After completing 3 full fastfood cycles (12 chests: 0→A→B→C × 3), a 4th star appears — bigger, pulsing, beckoning
• Player must sustain 100% fastfood tempo for 3 minutes to unlock
• Rewards permanent 5x click multiplier (applies to both manual clicks and auto production)
• Extravagant celebration: rainbow overlay, 24 god rays, 32 sparkles, 45 flying bitterballen, screen shake
• "BEK VERBRAND!" reveal text with "5x CLICK POWER — VOOR ALTIJD!" sub-text
• Achievement: "Bek Verbrand" — one-time unlock, persists across sessions

New: Vette Shit (5th Star Mega-Ultimate Tier)

• After Bek Verbrand, player must complete 3 more full cycles (12 more chests) to reveal the 5th star
• 5-minute sustained fastfood tempo challenge
• Rewards permanent 25x click multiplier (replaces the 5x from Bek Verbrand)
• Insane 12-second celebration: background flips via CSS transforms, repeated screen shakes, 36 rainbow god rays, 3 waves of 88 sparkles, 120 bitterballen + 80 frikandellen flying everywhere
• "VETTE SHIT!!!" reveal text with rainbow cycling
• After completion, fastfood tier counters reset to 0 and tier stays on C
• Achievement: "Vette Shit" — one-time unlock, persists across sessions

New: Autoclicker Detection

• Detects autoclickers by measuring click timing consistency (coefficient of variation) over 20 seconds
• If CV < 0.12 across 30+ clicks, triggers penalty: large carrot emoji overlay with "autoclickers mogen alleen wortels"
• Initial penalty: 10 seconds; re-detection during penalty doubles the duration
• Clicking is disabled during penalty

New: Bitterballen Werpen Minigame

• Added second minigame "Bitterballen Werpen" (throwing) alongside "Mosterd Dippen"
• When minigame charge fills and player holds, a random game is picked (50/50)
• Werpen is a power meter: hold to charge throw power, release for distance
• 0-65%: Weak throw (5-30m)
• 65-85%: Strong throw (35-50m, peak at 75%)
• 85-100%: Overshoot (25-10m, too much power)
• Distance converts to click multiplier (distance / 25, max 2.0x) active for 10 seconds
• Buff stacks with fever, mustard, and auto-clicker production
• Green/blue themed UI with countdown timer bar
• Added "Eerste Worp" achievement
• Ready indicator text changed to generic "Houd ingedrukt om te spelen"

New: Nationale Hap Level

• Added 4th level "Nationale Hap" unlocking at 10M bitterballen
• Uses /img/levels/foebele.png as background
• Introduces dual frituurvet: two oil pans that decay independently
• The best (highest) pan counts for the production multiplier
• "Ververs" button refreshes whichever pan is lower
• Second pan bar appears side-by-side when reaching this level

Changed: Frituurvet Cost Scaling

• Frituurvet refresh cost now scales to 5% of current score (minimum 500)
• Button text updated to "Ververs (kost X)" to clarify it's a cost

Fixed: Tour Popups Not Triggering

• Fixed fastfood tour not appearing when the meter first unlocks
• Root cause: addScore() was showing the fastfood meter before the tour wrapper in trackFastfoodClick() could detect the hidden-to-visible transition
• Removed duplicate meter show logic from addScore(), letting trackFastfoodClick() handle it

Fixed: Minigame Result Blocking Clicks

• Added pointer-events: none to mosterd and werpen result popups
• Result text no longer blocks clicks on the bitterbal underneath

DevTools
