Generally, I like this game. However, there are definitely some major problems.
The biggest problem is that the developer's website is a Facebook page. I don't have a Facebook account, so there is no way for me to provide feedback. The only recourse I have is to write this review.
Another, very troubling problem is that the ads come on and frequently start blasting at a high volume. This, despite the fact that I have the volume turned OFF!!! If anyone near me is sleeping, I can't imagine they'd possibly sleep through that racket. On top of that, it's jolting. Imagine you are in a quiet room, going about your business, then out of the blue AN EXTREMELY LOUD AD STARTS BOOMING IN YOUR EARS!!!!! I certainly don't mind ads. It's part of the price we pay to be freemium players. But that's way over the line of decency.
There are some other small problems, but I don't want to go into them right now. Suffice it to say that if you run into something you can't fix on your own, you'd better have a Facebook account! Otherwise, you'll be left twisting in the wind - with the advertisements blasting away - indefinitely.
