crumb. | an ant invasion

Night falls on a human house. Your colony wakes beneath the garden — and the kitchen smells of sugar.

CRUMB is a strategy roguelite about greed. Rally your workers with pheromones, crack into the house through the wall, and haul stolen food back to the queen. But the humans are listening: every ant inside raises suspicion, room by room. Push too hard and the stomping starts. Keep pushing and a shoe comes hunting, the vacuum roars down a whole lane, sticky tape bogs your line, spray clouds fall — and at 100, the exterminator gasses your nest.

The house keeps its own hours. While the humans sleep, raiding is safe and rooms cool fast; when they wake, the caches refill but every ant is noticed. Raid the dark, ease off the day — and pray it isn't a boss night, when the cat prowls till dawn.

Survive the night and a hungrier, warier night follows. Pick a room clean and the humans stop restocking it — so tunnel deeper, wing by wing, from the back wall to the side house to the bedroom floor. Your decrees, stores, and survivors migrate with you. How many nights can your colony last?

• Read the house's pulse — a day/night rhythm every night: raid hard while they sleep, pull back when they wake. Pantry, kitchen and living room heat up separately, and the humans remember the bodies you leave behind.
• Boss nights every fifth night — the Cat that never tires, the Toddler stomping everywhere, Renovation Day when no room ever settles. Outlast one for bonus royal jelly.
• A full house of hazards — feet, shoes, bug spray, the roaming vacuum, poisoned bait, sticky-tape barriers, and the cat.
• Three castes: workers harvest, soldiers bite back at the shoe, scouts reveal the dark house and sniff out poisoned bait.
• Queen's Decrees: 14 upgrades across 3 ranks, a free draft each night, one-shots like Tunnel Network and Second Queen, and repeatable gambits like Bribe the Dog.
• A campaign of wings — migrate deeper into the house; find water in the bathroom to heal your queen.
• Royal Jelly lineage — every colony you lose banks jelly toward permanent upgrades, so the next run starts stronger. Death is progress.
• Reactive lofi soundtrack that slides from chill to hectic as suspicion climbs — every note and sound synthesized live, zero audio files.
• Chase the badges — Pacifist, Ghost, Dynasty — and a local scoreboard of every colony you've led and lost.
• Easy to start with a 20-second first-night guide, hard to master. Includes 3 difficulties: Picnic, Backyard, and Exterminator. Browser-native, with runs lasting about 10–20 minutes.

One rule the colony learns fast: the humans don't get suspicious of ants they never see.

Note from the dev: CRUMB is a single HTML file — every visual is drawn procedurally on a canvas and every sound is synthesized live in the browser (no image or audio files, no AI-generated art or music). An LLM assisted the code and in-game text.
