Unfortunately i am not able to go progress... "5" button is not working... Am i doing something wrong?

PS <3 LOVE2D <3

I was kinda confused at first, and even won one time just figuring out the controls and moving the character around xD
But the characters levels was a cool idea, would be cool to see it in more deliberate levels like in a puzzle game, instead of all characters just moving around and catching you by surprise. 

I really liked the zombie transformation animation! But some of the graphics were not completely true to the restrictions. 
In the end, it's an enjoyable little game, congrats :)

There doesn't seem to be any guides on what the controls are or what is your objective, but once you figure that out, it's a nice, short game!
