Every room hides 3 numbers — the Cube’s only honest words. They say if the room is EMPTY or OCCUPIED. Whatever occupies a room is always, always hungry.
✨ GREEN ROOMS ARE CORPSES
All 3 numbers mixed (6, 10, 12, 14, 15…) → GREEN. Whatever lived here is freshly dead. Step in — but corpses don’t stay that way forever.
🗡 RED ROOMS REMEMBER
ANY prime (2, 3, 5, 7, 11, 13…) or prime fused to itself (4, 8, 9, 16, 25, 27, 32…) → RED. Something lives inside. It knows your footsteps. DON’T go in.
🔪 ALWAYS LOOK, THEN DECIDE
Press E to open a vent. The numbers glow GREEN (empty) or RED (occupied — it is aware of you now). Red? Back away. Choose a door that isn’t trembling.
🗜 WHAT YOU OPEN, IT REMEMBERS
Vents stay open behind you; you can always retreat, sobbing. Leave escape routes open — the Cube has seen you run, and now it will start closing doors on its own.
🕛 OVERSTAY AND IT TURNS ON YOU
GREEN → WHITE → ORANGE → RED. The floor starts breathing. At red, the Cube decides you stay — and takes you apart floor-up. Move before it turns.
👁 IT EATS ITSELF EVERY 30 SECONDS
The whole Cube reshuffles. A room you cleared a minute ago is a trap now. Re-read every room after every shift. Trust nothing twice.
🌏 THE BRIDGE IS THE ONLY EXIT
One room hides a glowing BRIDGE. Walk out — you escape. Fewest moves = your name in the Hall of Escapes. It has waited a long time for your hands.
🜥 THE EDGE IS HUNGRY
Edge vents open onto OPEN SPACE. Step out and you drift forever — never landing, never dying. Only the bridge leads out. Do not test the void.
🧠 REMEMBER YOUR HANDS
W A S D walk • CLICK look • E open / close. Controller: L-STICK walk • R-STICK look • A open / close • X climb up • Y climb down. Multiplayer: first to crawl out the bridge vent wins. The rest are the consolation prize.
THE CUBE
A sealed cube of rooms joined only by vents. The room you step into is green - you're safe. But linger and it fades
white, bakes orange, then burns red as the Cube purges you to death. Walk through an open vent
to travel - and the vent stays open behind you, so you can come back the way you came any time you like.
Edge vents open onto open space - step off the Cube and you are lost, unless you reach the bridge and walk out to win.
Multiplayer: everyone shares the same cube - first one through the bridge vent wins. W A S D walk • CLICK view look • E open vent • CONTROLLER left/right sticks + A
