This was a pretty neat racer, there aren't a lot of these type of games on the early portal. Very fast paced, in fact a little too much so, it ended up being more of a memorization challenge than a racing one, but it felt pretty good to play. The way things sped by were satisfying, even with the little sound each time you got past an obstacle.
If there was more game play, or maybe a map of the oncoming obstacles in the bottom right, I could see this scoring much higher.
