I was wondering if anyone could help me with a timer that counts down from 20 seconds in which if it runs out you lose the game. I also what to create red blocks and blue blocks for my car to pick up. once my car picks up all the blocks u win the game unless u dont make it under 20 seconds. If you hit a blue block u lose and if you get all the red ones without hitting a blue before the time runs out then you win. Anything you guys can give me would help. thanks!
