For this round of Ludum Dare, I made a silly little spaceship dodge-'em game involving relativity and ice cream. Check it out at http://www.ludumdare.com/compo/ludum-dare-27/?action=preview&uid=7355 and feel free to leave feedback! I’ll have more to say about it in the next few days, but right now I’m exhausted and a bit burnt. 
Did anybody else do a Flashpunk game for LD48?
