Thanks for trying it out, !
Yeah, i didnt even think of those issues you found out because i was more focused on handling the possession of multiple cars in the same level. It has been asked a couple of times before and even though i helped some folks out nobody bothered to turn them into a tutorial(even though i asked so nicely!) so i decided to do it myself. -_- I can add those features later on, and if anyone happens to add them before i do feel free to post here please!
