[FMX] Game clipping problem

I’m making a game. Think Bust a move on a see saw. you shoot colored balls at the board, but if you have too many one one side, the whole board tilts in that direction. I’m having a problem with clipping, especially when the level is tilting, the balls “hit” when they arnt actually touching.

Any help would be great.
