The game is decent, the art is good, and the I like the music but I seemed to encounter an error where the player can't move after I've pressed Q? Also, when you publish games to itch.io, there's a setting to set viewport dimensions, so I'd recommend setting this to whatever dimensions your game is in. (For most engines this will just be 1920 x 1080) because I cant see a pretty big part of the screen due to the viewport dimensions being too small.
Also, when I die, the music starts playing twice, so you'll probably want to fix that.
