@ mehmaster, Yeah all the midi files came from other games, usually the boss battles so that the pace increased with the level. I'm glad you liked it.
Okay, the three that really impressed me the most were;
OMGMAN - Absolutely beautiful, but difficult to get the ball going on different directions. You could pretty much get stuck in the corner with it going straight up and down indefinitely. Also, I wanted to be able to hit the bird.
Text Effects - This one made me want to learn more just because it was awesome and practical. Any game could be enhanced by some of the effects demonstrated here.
CollisionDetection - The concepts used here are over my head right now, but I was really impressed by how this was executed. Once I get a bit better I'm sure I'll be begging for a peek at the code.
My vote goes for Text Effects just because I felt it most demonstrated how just a bit of knowledge could be used to really enhance a project and I look forward to figuring out how to incorporate some of those effects in my future programs.
