I really like what's here! enemies dropping money when they die is very satisfying.
an issue I had was when I would jump in between two enemies I would get stuck between them in the air and would have to reload the page. maybe make the enemies nonsolid and give them a raycast so they stop behind their buddies? It would also make it so enemies wait their turn like some martial arts movies hehe
I'd also like it if movement stops when you attack, maybe only when on the ground
