What were other teams doing that you thought were cool?
Orymus3's -Delivery was probably my favorite game. The difficulty ramp up was perfect, and one heck of a challenge. And it merged the story line so effortlessly into the game.
The artwork in a lot of these games were superb. From pixel art (like JackOatley's - Mindfield) right down to awesome 3D animated models (like Mussi's - Diorma or Slaughterhouse Gaming's - Harvest). A level of quality you could expect in fully realized projects.
I'm still playing through all of the games, I've gotten through about half of them so far.
