I really like the art style for this and I'm a big fan of the colour palette too. Attacking didn't feel generic either which was great and I actually had to think in order to get damage off without being hit. One suggestion I have is maybe make it so the bosses cant attack for maybe the first 2 or 3 seconds because sometimes I would get hit as soon as the fight started although that might just be my fault. For your first ever jam game you did a really good job!
