I agree with the other commenter that the game feels! The hitboxes on the enemies were a little strange as well and i had to swing a few times before they dissipated (unless they had more than one hp? In which case a hit sound/animation would be nice). They also walk around off-screen where you can't see them if you stand too close to the front of the level.
But it is a cute concept for a beat-em up and the art is nice!
