I scratched together something with LÖVE, it's a platform jumping/tower game where you have to... jump up platforms :D

All the art I used was sourced from OGA, I credited the authors in the game description, but I should probably make a credits file in the source as well... anyhow. 

Not very complex at the moment, and the code is horribly dirty, but it works! (requires LÖVE 0.6.2 though)

Oh, heh, almost forgot to link to the game: Jumper

also, kick me if I didn't include propper attribution, it's the first game I've ever actually hosted up somewhere XD
