I didn't know the controls at firts, so it was a bit confusing.
I fall at some points where I think I shouldn't, so maybe It needs some rethink.
Also, the art of the characters and the background seems a bit off because of the different pixel size. Next time try to use the same.
But I think is kind of fun. And you make all the aspects of the game, its very whole for just one person, so stand proud!
