Press anywhere and drag left or right to slide your pinwheel along the floor. Lift your finger to fire a thread straight up. A quick tap fires where you stand. On a computer, drag with the mouse the same way, or use ← / → and Space. Only one thread can be in the air at a time.
Every cut takes one side off. A heptagon splits into two hexagons, a hexagon into two pentagons, then squares, then triangles. Cutting a triangle pops it. Clear every shape to finish the stage.
Each pop flings out a gold shard. It lands on the floor and fades after 4 seconds. Grab one to raise your multiplier by one step, up to ×6. Go 4 seconds without a grab and it slips back a step.
Cut shapes high and the halves fly up and away. Cut them low and they come down on you. A shape touching your pinwheel costs a heart and resets your multiplier. You have 3 hearts. When the fuse along the top burns out (60 seconds), the shapes speed up.
There are 10 stages, each adding one new thing: paper ledges that stop your thread, wind that pushes shapes and shards, a heptagon, a low ceiling, and a fast gold square whose shards are worth +2.
Scoring: heptagon 10, hexagon 20, pentagon 30, square 40, triangle pop 60, all times your multiplier. Clearing a stage adds 10 points per second left on the fuse, and finishing the run adds 500 for each heart left.
P pauses, M mutes.
