I'm pretty sure I don't have enough hands to play this game with keyboard, but I was able to make it work on controller.😅I guess you can't rebind controls on Pico-8, but might you be able to use the player 2 controls to make the controls a bit more reachable? I think if every control is accessible at once you can potentially make the game more challenging.
Overall pretty pleasant, and the on-screen level progress bar is much appreciated; I had fun with it!
