yea the hitboxes were a pretty huge problem the more i messed with them, and im not entirely sure how to fully fix them. if you look at the game page you can see ive put it in the Known Bugs section. The enemies also get knocked back when they hit you to give you a bit of breathing space, which is probably why they seem to hit you from so far away (just a guess)
I also put the absence of any music on the Known Bugs section. i was planning on adding some sort of background music, but i couldn't find anything that fit the game's aesthetic/style well enough :|
But still, thanks for the feedback :)
