Love the look! The constant stream of lines dashing by creates a great sense of speed and the Zebra is cute and looks like it's really hauling tail. :)
Feedbacks:
The lanes could be made more visually distinct. Either by stretching them out, so each lane is visually wider on the screen, or by making the ground coloring of each lane more distinct.
Some more visual feedback for the collisions would help. The cut straight to the 'You died' screen works, but because everything moves so fast, I was sometimes left me wondering what I'd hit, or feeling cheated. Actually showing the zebra hitting the tree would at least visually confirm for the player that they hit something.
Difficulty ramp is sharp. Well, more like it starts hard, I wasn't good enough to really know if it gets harder. ;) Could maybe use a warm up phase just to introduce the idea of lanes, obstacles and coins before everything gets rolling.
Fun game though, which I had the skills to unlock that piggy! :)
