Continued the idle games marathon with three parallel agent runs adding player profiles, unlockable theme systems, and a Tauri desktop wrapper. Then pivoted to Kitty Box for a three-agent cross-review and full Phase 2 planning doc covering Candybox-style RPG minigames, a prestige system, and the Cheshire Cat as ambient narrator.

Profile System: Three Slots Per Game

All three agents implemented independent profile systems for their games. Each game now supports 3 save slots with separate localStorage keys (e.g. grindstone_save_1/2/3), a visible profile selector in the header, per-slot deletion with confirmation, and automatic migration of existing saves to Profile 1. Grindstone uses a modal, Idle Dread uses a top bar, and Number Go Up does hot-swapping without page reload. The key requirement was keeping play data and test data separate — now you just use different profiles.

Unlockable Themes: 5 Per Game

Each agent designed 5 themes that unlock through progression milestones. Grindstone gets Dark Dungeon (default), Parchment (Level 10), Blood Moon (first prestige), Enchanted Forest (Zone 4), and Golden Kingdom (100K gold). Idle Dread has Corporate Gray through Cubicle Beige. Number Go Up goes from Hacker Terminal to Golden Ratio, with the narrator mocking you for choosing "Corporate Sellout." All implemented as CSS custom property swaps — zero DOM rebuilds, instant switching, saved per profile.

Tauri Desktop App: 6MB for Three Games

Wrapped all three games in a Tauri v2 desktop app. The landing page is the entry point, with relative links to each game working naturally through Tauri's asset serving. Build required a dist/ folder and copy-assets.sh script to avoid Tauri bundling its own src-tauri/ directory. Final output: a 6MB standalone exe and a 1.6MB NSIS installer. Shortcuts created on desktop and Start Menu.

The Grue Easter Egg

Added an AFK easter egg to The Grindstone. After 2 minutes of no interaction, the hero starts nodding off with floating "Zzz..." bubbles. 17 seconds later the screen fades to black over 3 seconds. Then: "You have been eaten by a grue." Click anywhere to wake up — the game continues underneath since it's an idle game. State machine goes idle → drowsy → fading → dark, with any input snapping back instantly.

Idle Dread Pacing Overhaul

The "slow burn" was actually a machine gun. Random events fired every 25-40 seconds (now 45-75s), notifications every 12-20s (now 20-35s), social feed every 6 seconds adding +2 dread (now every 15s, +1). Take a Break was ending in 4 seconds because it drained until stress=0 instead of lasting a fixed duration — now it's a full 30 seconds with a visible countdown. Break also suppresses all events, notifications, and social feed. Low-purpose dread reduced from +2/sec to +0.5/sec. The game should now feel like existential weight accumulating, not a popup firehose.

Kitty Box: Three-Agent Review and RPG Planning

Deployed all three idle game agents to cross-review Kitty Box from their domain expertise. Grindstone-dev focused on economy balance (rose garden is a trap at +0.05/s with escalating costs), idle-dread-dev on UX gaps (no next-goal indicator, no resource tension), and number-go-up-dev on click feel and achievement absence. All three independently flagged the same critical gap: no prestige system. The web-developer agent then implemented 7 technical fixes — innerHTML dirty flags, offline progress multiplier correction, consolidated saves, rose rebalancing, dev panel, and more.

The big insight: this entire game is the prologue. It should spontaneously transform into an RPG. The planning doc at kittybox/PLAN.md designs 5 Candybox-style minigames (Caucus Race, Queen's Croquet, Card Soldier Gauntlet, Jabberwock Hunt, Tulgey Wood Expedition) that are stat-driven and grindable — following the Candybox formula where grinding always works and skill just lets you punch above your weight. Character stats (HP, Attack, Defense, Speed, Vorpal) built between minigame runs become the player's RPG character post-prestige. The Cheshire Cat becomes the ambient narrator — his grin flickering in ASCII art for half a second then vanishing, commenting cryptically on purchases, and being the only character who remembers previous prestige runs.

What's Next

• Playtest all three idle games with profiles, themes, and the new Idle Dread pacing
• Kitty Box Phase 2 implementation: curiosities, reactive events, character stats, Caucus Race
• Cheshire Cat ambient appearance system across all Kitty Box locations
• Tauri release build with proper app icon (current is a placeholder triangle)
• Test battery updates to cover new profile and theme systems
