I love the colour palette! The UI, icons, character, and background all fit very well together (however you managed to convince stable diffusion to do that is beyond me). The gameplay was quick to understand, though towards the end of the level, I felt the difficulty had not ramped up as much as I would have expected it to. I was running it through Wine on Linux, so that may have adversely affected timers and loops.
Also writing this I just now realised that you designed the game to be one-handed on purpose, huh?
Anyway, fantastic!
