Seems really fun! Dude the music is a BANGER and the art direction was also really nice :) I think you nailed the game aesthetics-wise. Even the gameplay loop is pretty fun, bullet hells are really fun
on a separate note, I had trouble with controls but I refereshed the page a few times and it works now! It wasn't really a problem but seeing others comment on it made me think I should also mention it haha
Keep up the great work, hope uni doesn't get in the way next time you make something like this :)
