After playing for about 30 minutes, it is clear this is simply a money grab attempt by the game devs. Ads pop up at LEAST once per minute. It is completely unplayable without purchasing the ridiculously priced ad removal ($11). I spend quite a bit on games, so I'm not being a cheapskate here. If the game devs decide to fix this blatant attempt at ripping people off, I would be happy to give the game another chance and update my review.
