It's a good start. I was able to run beyond the screen, resulting in the game eventually stopping. Having to constantly stop running in a run game to make sure that you're at a comfortable difficulty or to keep from going off the screen is pretty annoying. It would make sense to give a fixed running motion and allow the player to move left and right, or--should you choose to keep it with the player having full control of the running--allow the player to run to the left as well instead of waiting for the screen to catch up. Another alternative is to have a fixed running point and left/right controls the speed at which the game runs.

Yaaaaaaay, Nihilism! :D
Not much of a game exactly, but I like it.

I actually like this, but it's painful to listen to (especially with headphones). I think the low end--particularly the bass drum--is very loud (probably intentional given that it's dance music). The synth effect of swelling and abruptly cutting off might be exacerbating it.

Definitely felt that swinging you mentioned.

Pretty awesome, dude

You might want to consider more than just bass and drums backing up the solo guitar though...it sounded kinda empty. Good job overall.
