Ads too repetitive and too long. Don't mind ads in an unpaid app, but if I haven't bought the game an ad is about after seeing it for the 1st time, I'm still not going to buy it if you show me the same ad another 100 times. In fact, it'll make me hate it, to the point where I download it for the sole reason of giving it a bad review. So repeated ads end up having the opposite of the intended effect. Are you listening, Microsoft?!?!?
