I love this game, but eventually you get to where the time you spend watching ads is longer than the time you can play. They don't even give an option to buy your way out of them. If they got rid of the forced ads and just left the optional ones for materials, I'd give it 4 stars. If they let me pay two or three bucks to get rid of ads completely, I'd give it 5 stars. But in its current state? It sucks but I'm going to have to uninstall it.
