Nice runner. I like the fact that I can change shapes, I think you have a cool core mechanic in there with it, like forcing you to be more precise with the shape you need to move forward. I liked the level generation and feel of speed.
Thanks for taking the time to play my game, I really appreciate it.
That's one of the things I'm hoping to address with cleaning up the levels a bit. Put more planning behind where everything goes, and how the different shapes can help/hurt you along the way.
