Kill the toast zombies

This is my first game jam game ever. 

You are a stickman who needs to kill zombies which are toasts with toast as a weapon. You are a true hero if you make it to the end. 

I had fun making it but it didn't come out as I wanted it. Anyways I hope you liked it and feel free to comment on my game.

You can move with WAD (jump with space or W)

Small hint for level 1. You can wall jump at the end.
