Okay I really want to like this game, but something about the controls is that I can't really get into it. First the jump should be RMB, I had quite some trouble with getting this right. The other thing is that the sensitivity is kinda high. Moving the mouse just slightly to switch the lane is either not enough or too much and I end up crashing. Maybe you could add settings, so players can adjust the controls to their needs.
I love the atmosphere and general feel of the game. It has quite some potential and I'd really want to play it more. Hope this feedback helps you.
