Pump to stay airborne and thread the gap in every zipper. One touch of the teeth or the mattress ends the run. Every zipper cleared is points, and the pickups floating between them pay extra.
Keyboard
Space, W or the up arrow pumps - taps, not holds. P pauses, M toggles sound.
Touch
Tap anywhere on the field to pump. Rhythm is everything.
Worth knowing
Every pump is the same size, so height is a rhythm, not a hold. The gaps tighten and the world speeds up the deeper you go. Blue pills pay points, lube slicks you straight through the teeth while it lasts, and a heart banks a save that flings you back up instead of ending the run - you can hold two. The mattress is not a soft landing.
