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.

Hello, this is the Underdark Development Team. We’re sorry the microtransactions and incorrect descriptions caused frustration. Issues like incorrect pet/prop combination text will be reviewed and corrected. Thank you for the feedback. E-mail: libertydust@gmail.com

The game is great, but not the monetization. If you like tower defence &/or RPGs, you will enjoy the game. You don't just build towers, but you also control a character. However, after about the 20th stage and 10th special stage there's a difficulty spike. A more advanced game that you buy and play without microtransaction would cost 10-15$. Here removing ads is over 8€ and speed up function 5€. But that's far from enough to advance. If these 2 together were 8€, I'd consider it.

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.
