During the 52nd Ludum Dare game jam, we've been creating an arcade space shoot-'em-up with LITIENGINE - Star ReaperZ.

Check it out on the LDJAM site!
And of course, the game is open source, so visit the code repository on GitHub and admire some hastily hacked jam code - just for the hell of it :)
Who knows - maybe you'll even get some inspiration for your next litiengine project?
