I absolutely loved it. I played for a day and realized it would be bad for my life as I would never get anything in real life accomplished. Minimal adds. Game play is smooth. A lot of options for boosts, freaking FUN! The best tower defense game I have played, hands down.

This should be called Ad Defense.

I feel like I spend more time watching ads than I do in actual gameplay. The game is difficult and requires quite a bit of grinding to get past the evolving stages. That’s where all the ads come in: ads for boosting fortress health, reviving from failures, ads for boosting every 10th campaign level, ads for joining events after your event tickets run out. And the worst part is that sometimes after watching one of the tedious ads, it’ll say “oops, something went wrong” and not give you credit for the ad you just sat through—then prompting you to watch another ad.

The gameplay itself isn’t horrible, but again, it requires a lot of grinding to level up every tower. Grinding, itself, isn’t fun—buy grinding in a sea of ads is unbearable.

So, I deleted the app.

I love the game, if you’re bored and want to kill a couple of minutes out if you don’t really know how much free time you have this game is great for that, because you can just pause and pick it up where you left off. But I can’t move past world 4. There are this blue guys that every time you kill one two more show up and they damage your base even though they’re nowhere near it, so regardless of what I do, when they show up I’m dead, which is very frustrating, I would like for the game to have some sort of guide with the different types of monsters you encounter and a description to try to find its weakness or how to kill it without dying.

Developer Response ,

We appreciate your feedback and our suggestion is to play the daily events to get more currency, open chests to gather turret parts, then upgrade your turrets. Also, bear in mind that every world has a recommended synergy, and some turrets are best at defeating a world than others. Perseverance will bring you victories! You can chat with the developers and the community on Discord to get some help on strategies:
