Attack of the 5-Foot Fish

The humans have polluted your home and turned you into one angry starfish. It's time to strike back.
Shoot your arms at the docks to send the people flying (your pollution-related mutations have made your body highly reactive with the air). Be careful! The other sea critters are hungry and your arms also serve as a tasty snack.
Left/Right Arrows: movement
Down Arrow: dive downward
Z: swim upward
X: shoot arm
This is my first completed game since probably middle school. The code is a mess, pls don't judge (or do, I'm not in charge of you). At the very least I've found some things I'd like to work on in my next project, but I hope people can get a little enjoyment out of this too!
