Levels are excessively luck dependent unless you have power ups. Ads are its own separate thing. I understand having forced ads occasionally that can be skipped or the option to watch ads to get power ups, extra turns, etc. But after every single attempt of a level you get an ad. These ads can't be skipped and are usually 30 secs long. Its beyond excessive especially if you're watching ads to get the power ups that you have to have in order to beat the levels excessive difficulty. Just a waste.
