This has promise! I found it a little frustrating but kept wanting to see more from it (e.g. variety of challenges/obstacles). If the playdate can handle the physics calculations for this, I’d like to see more momentum/rolling based elements like jump ramps.

A couple bugs I ran into:

• I can fly infinitely by mashing the jump button. This feels like cheating, but it was the only way I could pass some obstacles. It also allowed me to skip most of the obstacles and just come down to get coins, and fly forever past the end of the floor.
• sometimes I would jump while touching the edge of a platform and it would instantly kill me

A really neat idea. I liked the pressure of the black wall coming up behind you to spur you on.
