So I've been working on my next game, Speeder, for a while here. It is coming along well. It will be a top-down driving game where you use phone tilt to move your car left or right on the road, avoiding other cars and obstacles and collecting powerups to go faster and score more points. I like it so far and I think you will too.
You can follow my development of this game over at my blog, Infinite Improbability. I try to post every day that I've done some decent amount of work on it so that I can keep track of my progress a little bit better, and to keep me on task. It is sometimes easy to get distracted and do other things. Here are some screenshots of the current state of the game.
