I really enjoyed the game until the most recent update. I'm fine with ads as long as they're for optional rewards, but now you get bombarded with ads every 10 waves. (Thats 20 ads in a standard 200 wave playthrough, that's absolutely ridiculous!) It really breaks up the flow of the game and kills any desire I had to play it. Please revert this change

Everything was fine with this game when it came to ads being optional for rolls and a boost in resources if you wanted, but just recently, ads are being forced every 20 waves. And getting far enough into the game, if you reach Wave 200, 500, 1000, thats 10, 25, 50 forced ads that provide nothing other than being in the way and it just gets worse the further you go. Its already a slog to go for high rounds when it comes to how much time it takes. Feels like Im being forced to pay for no ads

Extremely good game, very fun, well paced progression. I would have given it five stars, but the game devs decided that the optional ads weren't enough, and decided to put in mandatory ads on top of that. I understand that you need money, but it makes your game almost unplayable when you have an ad in between every 10 waves... most people are perfectly happy with optional ads when presented with them, you literally chose to ruin your game with this update. Would be five stars otherwise.
