I liked the idea of this game, but the movement kind of made it a bit worse. I would like to have more control over the jump height, since it was now just jumping a set force, which made me miss a lot of the needed points. Very hard to get it right.
I was well in the negatives :D Quite a good idea and with some polishing it could have a nice gameplay, get some things you need to dodge as well instead of just trying to hit everything, to make it even a bit harder and some things you need to jump over on the floor etc.
But good work mate! :)
