I quite like the simplistic art style of this project, and the fight mechanic of jabbing in either direction. It felt challenging and like it could potentially have some good game feel.
Audio would make the world of a difference, as at the moment not enough is communicating what is going on. I'd love more clarity when I'm hurt, too - there seem to be bars in the top left corner, but this is too far removed from the centre of the action for me to pay attention to easily whilst also navigating the platforming aspects and enemies.
I think it might also be a better experience for the player to always spawn on a solid piece.
