3/12: 2* Way too many overpriced micro transactions. 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 silkmoth mode is almost unplayable. The load icon for unlocking towers gets bigger each time until it blocks the entire screen.

This is a great game, but multiplayer doesn't work no matter what my friend and I try, and playing with friends is the only reason he dled it. Had to knock off a star for that. Other than that disappointment, the game is fun and I love how many different towers, heros, and weapons there are to choose from to make the gameplay not just dumb luck. I wish I didn't have to go through so many menus after every level to collect all the perks. That's pretty annoying.

Thanks for your thoughtful feedback! We're glad you're enjoying the strategic variety. Sorry about the multiplayer issues—we're working on improving its stability. We'll also look into simplifying the post-level menus for a smoother experience.

Greta rower defence game with a lot of player choice. Ads are completely optional which i love. The only down side is the reward system. Don't get me wrong you get a lot of free stuff but it's behind so many different buttons it feels like ima need a secretary to keep track of it for me lol. Other than that, among the best games ive downloaded in a long time

Thank you! You shouldn’t need to hire a secretary to claim your loot 😂 We hear you about the scattered reward buttons and will consider ways to bring claiming together. Glad the battles and freedom of choice are working for you!
