If there's one thing I love about Greenlight, it's all the insanely creative people it attracts. Like the creators of this side-scrolling shooter, Shütshimi.
To quote the website, Shütshimi is "a randomised shoot'em up about a muscle-bound fish with memory problems defending the seven seas." It's a fast-paced game for PC and the 360 where you fight waves of enemy fish, during rounds that last 10 seconds each, using powerups that last 10 seconds each. The 10 seconds thing is what the "memory problems" part refers to.
