Oh wow, I remember playing Coil a while back. I was impressed with how it's controlled purely through mouse movements, no clicking or keyboard inputs at all. I never knew it was a McMullen game though. My actual first McMullen game was Aether a couple years back, but I didn't really know of him at the time. It wasn't until Time Fcuk that I really started taking notice of him, making that feel more like the first game of his that I had played.
Should be interesting to see where he goes in the future now that he's breaking into the console scene.
