I abosolutely loved this! Really reminds me of Rad Racer which I used to spend hours playing on the NES.
Controls are tight and the high speed racing feels really good. I also loved how you can change radio stations, each of the soundtracks are superb and adds to the replay value. I also really liked the 8-bit SFX, especially the crowd cheering sound at the start of the race.
Really good stuff! I will be playing this one again :)
