Chibi Soccer  
It's a really nice idea, though the sprites could use some more frames. It was kind of weird adapting at the controls at first, but then I easily picked up and managed to have a good match against the decent AI. The gamepad option is really nice, as well as support for 2 players. Good fun!

Simply one of the best games I've seen done with Allegro. Clever gameplay, funny dialogs(with a nice approach to voices), and an eye-pleasing art style. Nicely polished, and a game that inspired me to do a puzzle platformer as well.
