The game so far is absolutely stellar, the artwork, music and overall game feel is incredible. I will say, however, the controls do feel a bit strange. I feel it would be more fitting for jump to be z and attack to be x, I remember it being that way a while ago, so I'm not sure why that changed.
Please at least add a way to re-bind controls, or multiple set control bindings for the player to choose from.
Still a great game otherwise! Keep it up!
