Wow, this is really cool. I'm surprised this doesn't have more ratings.
There was a bit of learning involved in this game, but once I figured it out, it was a lot of fun!
With this sort of game, I expected there to be some sort of obstacle in the road, but I like how you made the twist be a limit on speed to encourage the player not to hold down on the accelerate button.
It was also really easy to get into and there's a bit of timing involved in figuring out when to decelerate. Well done!
