Cloudkid just blogged about some of the creative process behind one of our more recent games, Freestyle Fizz. Here're some images that show the concept sketch to final design of some of the levels in the game... I was responsible for the rough sketches and designs, which in turn get handed to another artist who finalizes them.
We also just released our newest game, Hardboiled! Check it out, it's got a 2 player mode so you can play with a friend... or cheat so you will always win. Whatever suits your style, I guess.
