Too many ads! Ruins the game. Excelent idea for a game, and the game itself is well done. The problem is ads. I have never in all my many years played a game with such persistant, frequent, intrusive ads. I know the developers have to earn a living, but you spend longer watching ads than actually playing the game. A level can take a few seconds to complete, and occasionally you can play a level with just a banner ad, but usually there is a 30 second ad per level, and sometimes 3+ per level.
