What part of "r for restart" do you not get? There's quite literally NO REASON to require me to use mouse for that, especially when I already need to use my right hand for the keyboard controls because WASD isn't available. For that matter, the car spins way too easily. Doesn't matter if I hold right arrow down, the car will still start to flip as soon as I press up.
As for the rest, the game is so generic I'm not entirely certain I haven't played it before. If there are some redeeming features(other than being functional - I'll give you that much, at least), I'm not seeing them.
