Looping Sandbox

My first time participating in LD! I really wanted to try and write the game from scratch including the game-engine, which turned out to be a little too ambitious given the time.
I didn't finish and it's currently missing pretty much all the game-play content that I had planed. Nevertheless, I think it's a nice mini game-engine featuring a mini demo sandbox game. :)
