Here's a list of all who helped in the colab project;

Slinks: Coding and just plain awesomeness
Yaloopy: Graphics and ideas
Paul: Snow sprites (we couldn't get in contact with him to ask permission cause he's not been online all week. Hope he doesn't mind)
Ed: Music and co-creator of the gloom
Bono: For being there for all of us in our hearts. I guess.
