High quality artwork, and a very creative use of the theme! I found that if I twist my arms around the keyboard I can make logical sense of the controls! It is very difficult to play, and the mushroom part scared me a lot. Thank god you can wall jump!
Imagine if the controls changed every single restart!
My only criticism would be that the attack range is very small, it's very difficult to actually hit enemies and I ended up just jumping over them.
