I'm afraid that for me this falls into the category of "it isn't actually more fun with only one button". I kept getting off a little bit and then having to restart the level. Maybe with a quicker respawn time? (though the death animation was a lot of fun). Or checkpoints? A nice start, though. And the level design was well done.

The circle pads should move only when you step on them. The last one on level 2 (or 3?) messed up my attempts. I liked how the design was so true to the core idea. Check our game: https://cerosware.itch.io/one-stick-shooter
