Slingshot Puzzle

Disappointed is what Im feeling, I purchased this game about 8 months ago and there wasnt any advertisements but with the update the developer is milking the system... Who knows are IAP coming soon !
Greedy greedy a $5.00 game is all it is worth but the frustration of having an ad popup during a precision shot is stupidity.
