A simple form of genius. This is a creative game, challenging, and addictive. The old-school look is great for the arcade feel, the music is perfect, and the motif is great for a game-oriented community such as Newgrounds. It's an easy game to learn, but tough to master.
The random element of the game is a fantastic idea, because it keeps the player from memorizing exact patterns and offers a different challenge every time. Some configurations may just be unbeatable to the timing and placement of the obstacles.
The only problem I noticed: once, I intentionally came to a stop between the peaks of a double-hump and was unable to create enough momentum to free myself from it. This is fair way to lose the game, but there was no way to reset. I had to reload the page, which can be annoying. Perhaps add a reset or title screen button?
