4 stars: Incredible game with unique features. Although there are some minor bugs and expensive in app purchases. For older devices you may experience lag or even not run on your device. In addition, there are no ads unless you want them. Overall, it's not pay to win and you can progress without spending a cent.
4 stars: Amazing. Tons of rewards and quests and achievements daily for f2p to stay engaged. Tons of things to do as well. I'd give a 5 star but I cannot stand having to click CLAIM Twice every single time, for every single achievement. Make that a one click claim please! Otherwise I love this game and the controls, interface, etc are super intuitive.
3 stars: It's a good game and all there are a couple of downsides I have to say, there is no recall of all buildings, you have to individually pull all of them back, no masd upgrade, and it doesn't really sort out the toughest from the weakest, if you could improve that aspect of the game it would get 5 stars from me. Love the game though
5 stars: Good game so far. I'm only on level 3-2. Not too many ads, which is a nice change. You can actually play the game for once. Good game concept, equal levelling so far; so no replaying levels over and over again to move on. It's a New concept to tower defence games and they've done a good job so far.
5 stars: It's a good game, I really like it so I'm gonna give it 5 stars despite a few things. It does balance the ads well as well and that's a big deal these days. ...
