Really cool racing game!
Going in I thought it would be more of a bland game where you just win races for the hell of it, but it's more than that. You actually have to drive, navigate the world, and make smart decisions so you can get to your destination effectively. I wasn't aware of this an ran out of gas in the middle of the road... That's a really unique touch! Making the player think about how they drive and setting up consequences if they don't.
My favorite part of the game is the music actually. There were some silly tunes, rockin and groovin ones as I was playing (and I love the Wii Sports-style vocal sfx!) The singing at the beginning caught me off guard and left me rather impressed, did you book a band to play for the game? It's a satisfying and fitting feature to the experience for sure.
I found no real problems, everything ran smoothly. Great work guys!
