A local multiplayer where the light is either your enemy, or your weapon.
I just started using Unity at the start of March and I took this opportunity to teach myself the lighting engine. This was the first game jam I've ever done. That said, everything in this game is broken :( My main mechanic broke at the end. You were supposed to be able to cycle between the lights, but nope. It isn't really anything. But I learned something, right?
