this sprites are looking super crisp, i really like it, also like the base resolusion you went with to get this insane nice retro vibe. I missing something in the combat scenes fighting back and forth. Something like the char is charging the enemies on attacs and visa versa to make it look more dynamic. I know its a jam, so sometime we cannot implement all we would like, but in your case you got a pretty solid foundation to add a few more feature to have a even nicer game. The music are also wonderfull and are matching the vibe the game gives me.
Which kind of font are you using for the text ? It looking rad.
