The intro is great and I liked the innovative take on the chrome dinosaur! It's like a no-internet game... but it makes me feel bad.
I agree with the other comment -- the music feels like a mismatch. I would expect something a more somber given that we're chucking lizards at a wall to start a run.
Other than that, my only qualm was that I had a really hard time timing the jump. It felt like it went up higher than I anticipated and I never made it over the obstacles. Otherwise, I liked that there were obstacles to keep an eye on in both areas of the screen. Using both the shadow and the treadmill was clever, and it would be really cool to see a platformer in this style.
