It's colorful, funny and well done. GJ
+ I like the style: kinda like high resolution pixel art ? ;p
The only problem for me is the control for jumping: the Z key.
For me 'Z' is where your 'Y' is. So it's like playing with X+Y.
Many in countries EU don't use QWERTY keyboards.

A+S, S+D, K+L ... would have been a more international choice.
In the future, it would be nice if you could keep us, EU players, in mind. Thanks :)
