ZERO STARS!!! Ads ads ads and oh look, more ads. An ad after every single level, obviously annoying. Sprang for the triple cannon with no ad bonus, $10.59 with the tax and nothing at all happend in the game, no cannon and still ads out the butt. Sent 5 emails to support about it, gave it 3 days and not even a reply. The leader board doesn't seem to mean anything. Soooo much wrong with this game and the developers. Don't waste your time or money
