The tutorial only has 2 layers. One has the game and the other has the score.
I cannot change layers because that would put me looking at the score box.
If I choose Destroy, it destroys the monster that has the collusion and leaves the rest to go around and multiply.
There must be a way to end the game.
It is evening here so I am going to shut down for the night. I wil be back online again tomorrow.
