Platcore is an avoider game where you play as a Platbot, which is a testing robot for Platcore. Platcore will be using you to test their newest products, which come in the form of things which aren't friendly (lasers, turrets, even bigger lasers... you get the idea). The game's soundtrack is synced to the Platcore AI, so when the soundtrack goes boom, something else is going boom, and it's likely to hit you in the face.
