Justice For Zero

"Did you ever want to divide someone by two who tried to divide by zero? This is your chance!"

Help the cop to get rid of some ugly monsters who are attempting to destroy everything we know by dividing by zero.
Your only weapon is an odd cannon shooting regular expressions until eternity.
Good luck!

This game was made in around 6 hours for Mini Jam 46, all music/pixel art was made by me, some general purpose code was reused from former projects.
