This was a fun bit of chaos! At first I expected spacebar to just make the character jupm like a normal platformer, so I was a bit confused that it did not at first. But after a while I understood that the game has a skateboard-game like combo system, combined with a zombie shooter. A really cool combination that I have never seen before! Once I understood the aim it was a lot of fun to jump around and do those edge-slidey moves (what are they called again?) whilst shooting zombies.
If I can give a tiny bit of feedback on the menu. I was a bit confused in the level-select screen, because the first few levels were shops and character customization places. In the end I figured out that the actual levels were behind those, but maybe it would be good to put the actual levels first in the list. So that people can start playing immediately, with as little friction as possible.
This was great fun, thanks a lot for making it! :D
