The game was super well polished. The different color palettes were a great idea for accessibility and the music was lovely. Level design was really cool too. I felt like there was a good flow to it.
My only nitpicks were that the controls were a tad difficult to use for me. I think changing ZX to JK or something of the sort so I can use both hands and I was a bit annoyed with the wall jump happening when I wanted to just jump on top of something.
