Liked the idea a lot. Controls just took a little to understand, but once I got the hang of them they were fine. The design was basic but clean.
I wish the sporadic enemy gave a few hints as to what it was about to do... Like a warning before it goes into fast speed. Seemed that in order to win I had to do a lot of short safe plays, if the enemy gave different types of warnings you could use those to be a bit more daring.
