I entered Ludum Dare 37 this past weekend, and I used Unreal engine to make my game. I had to create the game from scratch (art, code, and audio) in a 48 hour window based on a theme. The theme this time was “One Room”. I made a game called “Roomba Fight Club”. It’s a local multiplayer game about fighting Roombas and wrecking a house. You can download it for free here:

Just wrote a postmortem for the game if anyone wants to read. http://www.undeaddev.com/the-second-48-hours/
