HITFRAME

Drag a selection box around anything that moves, and the box that wraps it becomes a solid neon block. HITFRAME is a puzzle platformer about hitboxes.

The box stays alive. It is recalculated every frame from the real position of what is inside it: wrap a spinning propeller and the box stretches and shrinks as the blade turns, lifting you to the next ledge like an elevator. Wrap two small stones on either side of a pit and you get a bridge. Wrap a swinging pendulum, a bat in flight or a falling stalactite and ride it. Anything inside a box can't hurt you, and a box laid over spikes keeps your feet safe.

You get two boxes at a time. Drawing a third removes the oldest, and you can dismiss one whenever you like.

30 levels in 3 worlds

• Workshop: propellers, pendulums and stones.
• Cavern: bats, falling stalactites and spike pillars.
• Factory: conveyors that carry you, pistons, and the Overseer, a boss you lock away with both boxes at once.

Each level has three stars: reach the exit, use no more boxes than par, and beat the par time. The first levels show you the move with a ghost box, no reading needed. Your progress is saved.
