I took all your comments and re-edited the game. The controls should be much better now! (with special thanx to Tom Fulp, Tom, Thanx-a-Lot, Park-a-Lot!!!)
I also sized down the whole thing so on slower machines it should be better to play!!
And... For mac users (and everybody else) the "get out of the car" key is no longer "Insert" but "BACKSPACE"
HINT: It is not necessary to park a car on it's parkingspot!!! It is preferrable though because you won't loose track of which car is who's!!!
