5 stars: I don't know what everyone is talking about having to purchase power ups to pass lvls 60 and above, I am on lvl 100 and have not had to purchase any power ups, its a strategy game, so use strategy and not simply attack here and there. I like this game very much, it is a good pass time and it gets challenging as you progress. I would give it 10 stars if I was able to.
4 stars: Really dope in all areas, very entertaining, a total time killer that'll kill hours. However there are some areas of the game that need to be explained into more detail. I had to figure most of it out myself which wasn't hard for this app. But also there is NOT a help or FAQ option. I personally would like to know what the voyage upgrade does and have no way of really finding out.
3 stars: Not a bad game and can be quite addictive. But the developers really need to fix some bugs badly. It's really frustrating when the game dies when you try to use a booster. Sometimes it dies just because. Fix that and it would be worth at least another star.
2 stars: Two stars because I love games like these but I took the rest of the three stars because it's a cash grab, there are countless levels in the game that were made with the sole intention of pay to win, you can watch ads to use power ups but conveniently those don't load up on some levels, also there is no way to check your progress. So get the game it's fun for a day or two after which you should delete it.
2 stars: It's fun for a sec...
