"I made this for my programming class. Problem is though, is when the turkey sprites are suppose to follow the mouse pointer until they reach the destination (table) or hit one of the sides (black lines) the script should restart. Instead of even following the mouse pointer, right when the numbers count down and the game should start, instantly the game screen disappears and it goes back to the interface. Like I said before, it should ONLY do this when a black line or the table is touched. Can you tell me what I did wrong?"
