I Broke the Thing - Bruce Hill

Controls: arrow keys to move, z/x/c to speed boost/jump/shoot.

I Broke the Thing is a beautiful mess of a game made with Team Danger for Global Game Jam 2012. You play as an alien vending machine repairman who breaks the thing, causing a rip in spacetime. The only way to prevent your space station from exploding is to travel back in time, fight your way past your past-selves and get to the time machine at an earlier point in time, in order to send yourself even further back in time. Once you go back far enough, you can prevent the thing from breaking in the first place. Surprisingly fun to play once you get past the poorly-explained premise.
