Here's my completed first (using C2) game:

its a game about a cute tiny piece of poo <img src="http://forum.tgmonline.it/images/smilies/asd.gif" border="0"> that runs and jump over some buildings trying not to fall down.
at the moment is up on Kongregate:
soon I'll upload on Scirra Arcade too..
I found it very nice to create it this using C2, at first i thought it could be limited or something but then everytime i found a problem or had a doubt on how to solve something i always found a perfect soulution in some topic here!
hope you'll like the game.
