Hey,
This game is quite awesome to play. Quite an interesting concept and the presentation looks cool. However a few things to polish up here, first, the level of difficulty should increase gradually, making it too high at the start ruins up the feel of the game, Secondly, The distance text on the right-hand side of the screen hides away the obstacles and give a very few sec for the player to recognize the obstacle which is weird too, so replace that somewhere else. Also, after restarting give some delay so that the player could get enough time to prepare. Next, you can increase the speed gradually which might look cool.
