Shark Vs. Pollution (Unfinished - Read Desc)

Well, I wanted to do a thing where your shots could destroy the pollution, however I had no idea setting up a collision system could be so hard, if only there was a simple command in LÖVE2d that handled collision between two different coordinate combinations, would be so easy.

Anyway, sorry about that.
Please be fair on my noobiness, I tried my hardest :)

P.S: I made the sound effects with my mouth :O (Not the chiptune though obviously)
