Lots of fun so far!

No in-app purchases! No ads! And its a lot of fun! Wish all developers would take this approach! Still have to play it for a few minutes every night even after being about halfway through the second tier. AI is not too bad. Win most races on first try so far. Occasionally takes a second or third try to win a race to keep it interesting but at least its not so onerous you have to play each race perfectly to win. Hopefully, the developer keeps updating (without ads or IAP). If so, Ill probably be playing for a long time!
