At first I thought it was going to be a text adventure and then it morphed into a Trials-style bike game. :) It took a little while to figure out that up makes you go forward but after that it wasn't too hard. You get a good sense of speed and I liked the loop at the end.
The R restart button came in very handy!
Is that Prokofiev's Dance of the Knights I'm hearing on the second part of the game? I only know that because I listen to Hollenthon.
