A simple boolean/variable limiter can make it work. But I'll just stick with number variables and I'll use the touch object instead of the mouse but it still works the same with the mouse object.
Global Number Variable named "ClickCount" .
*On Touched Object1
. -----> Add 1 to Global Variable - ClickCount.
*ClickCount less or equal to 2 & *On Touched - Blow Tile.
. -----> Call Function ("Blow")
