The game is okay, but I find a major problem with the fact that the game wants you to go fast, but you don't give the player enough time to react to what's going on. It would've been better if you shrunk and extended the screen so that the player could see far enough ahead to react to everything (or maybe scrolled through the entire level to show the player). If you don't do this, then it just comes down to memorization, which is annoying, and even then, the speed of the character changes too quickly to get through the levels flawlessly. Even after getting an extremely good score on the first level, it wasn't even half of what I needed to unlock the last level. The game could be really fun, but the difficulty of the levels rises too fast (it would've been cool if the first level was just filled with pins and speed strips).
Still, I like the novelty of it and definitely think you can make a really good game with enough time. I wish you luck on your next gaming endeavor.
