You are a small hero trapped inside a huge mysterious house with endless floors. Each level presents a room with three floors connected by ladders. Find the key, collect all the gifts and reach the exit door - but various enemies patrol between you and freedom.

The house consists of four room types that cycle through: living room, kitchen, bathroom and storage room. Each cycle changes the color palette and wallpaper pattern. Odd levels are dark with atmospheric lighting, even levels are bright.

Eight enemy types with different movement patterns - some walk along platforms, others bounce, some hover in sine waves, others move in groups. Enemy speed and count increase with each level.

The key is always on the top floor. The door stays locked until you collect both the key and all gifts. Every 5 levels a bonus heart appears for an extra life. You start with 7 lives.
Each level is procedurally generated - ladder positions, enemies, items and decorations are recalculated but the same level always looks the same.
The number of levels is unlimited. How far can you climb?

Controls: WASD or arrow keys to move, Space to jump, P to pause, F2 for FPS, Escape for menu.
