Bombercat was a four month game where a group of 10 programmers had to build a game engine from scratch and then build two games that were supported on the framework. We made an Arkanoid clone, and Bombercat, a Bomberman clone. As the only artist of the bunch, I was tasked with art on top of my other duties...so it was a very full four months. All the sprites were created in Adobe Illustrator.
