It's a great game and I think the mechanic of speeding up when you changed level was really cool, but I do have one or two complaints, it might be I'm bad at playing car games but I do think it was a bit to hard, I feel like after the second level you went way to fast, its still a great game either way but it might be chalked up to me being bad at the game.
But as a plus the art and the audio for the game was really well made and I feel like with a little bit more polish it would have been an amazing game.
