This is the worst ad fest I've ever played. I didn't even play 10 min and got about 8 forced, full-screen, game-interupting ads. This is unacceptable. The fact that this game has a rating of over 4 stars at this time is mind-boggling. I've spent more time looking at ads than "playing" this trash. And as if this is not enough ads, there are optional ads you can watch over the ones that are forced every minute for small quantities of materials. Remove those forced ads and I might reconsider.
