Lotsa good stuff, very impressive.
Giro was the winner to me. Since this was a programming contest, and not a game contest, I think Giro represented the slickest bit of coding overall, and it did everything (graphics, sound, effects etc.) very well. Smooth movement and no clicking to the sound at all. I would love to see Giro developed into a full game. Please Franz, don't let it end with just this demo.
I wanna see Giro: Full Version on JoyGP someday for $15!
Slyro is my next fave. The game is very fun, and that music. OMG! It's fantastic! Best game music I've heard in ages.
Gloop - top quality Lemmings style game in the making. Another one that could become a commercial game with some work.
Falldown - simple and fun. Nice.
Drunken Frogger - clever concept, and solid execution.
Those were my favorites. The Chip-8 emu is cool too, just to have more emus on GP32, altho it's not a system that holds much interest for me. Lotsa other good stuff there. I wonder who'll win?
