I like the idea - definitely needed more time to get some more things working and making the game feel a bit more dynamic (I think having audio in a turn based game helps a lot pass the time), but I especially like how you managed to incorporate the idea of a racing game in a deck building mechanic. I think having a tutorial or a more linear progression to introduce mechanics could help as well. This also very technically impressive and there's a lot of cool design ideas for the cards. Great job!
