Absolutely phenomenal tower defense game. I have only seen ads when I intentionally tap the advertisement buttons for various rewards. This is one of the best mobile games in terms of free to play enjoyability, but there are packs that you're able to buy with irl currency, however nowhere near needed and decently cheap if you want to get a little boost.

Pretty fun time waster. It pauses on level ups, so you don't accidentally die. Definitely the best td I've played in a while

This was a really fun game, and I think I'm going to keep it around. It has numerous optional ads for various in game boosts and rewards and even an ad reward system, but it seems like you can ignore those if you don't mind the grind. There are also several—SEVERAL—prompts to buy various season passes hero passes battle passes tower passes. It's pretty off-putting how hungry for my wallet they are. I thought about buying the ad skip option, but I don't think we should reward this kind of behavior

3/12: 2* Way too many overpriced microtransactions. There's 2 battle passes for 1 season. Lots of text is incorrect. For example, pet combination says 2 pets but actually takes 4. Prop combination says it takes 2 pets... and there's an energy mechanic. So much wasted potential for the actually enjoyable tower defense part of the game. 4/27: 1* Still no fixes. Also, the silk moth mode is almost unplayable. The load icon for unlocking towers gets bigger each time until it blocks the entire screen.
