5 stars: It's an interesting concept implemented well. There are ads, of course, but they don't feel excessive or intrusive. It's quite hilarious though that there are many levels you can pass without doing anything lol ETA: I noticed a lot of other reviews on here talk about having ads every level and I'm glad they fixed that before I got here
4 stars: So far it's a good game. If course I have literally only played 4 levels. I hate when they ask how you like the game after less than 10 levels. It's like I don't know it's been a few levels. It's easy and not challenging at all at level 4. But I am not flooded with ads. So that's a good thing.
3 stars: This game is a good time passing source but I am annoyed by its intrusive ads every 20 or 30 seconds ... And almost all games in playstore has become incomprehensible and unworthy of playing due to annoying ads all around the place. Uninstalling Thank You
2 stars: While the game itself is fairly fun, both when making and destroying towers, the constant ads where they aren't needed is too much. Beat a level? Ad. Beat another? Ad. Want to play a mode that is basically only different in terms of end goal? Ad. Beat a level there? AD. I can understand the occasional ad and also having them for certain unlocks, that is fine, but the spam of them ruins the game for me.
2 stars: Decent idea. Way too many ads. It forces you to watch an ad after the level before you get the choice to watch an ad for bonus rewards for that ...
