Fun game but has been abandoned by the devs for another version. Avoid paying money for this as crashes are frequent due to lack of updates to current mobile devices.

Needs an update all the touch controls are off centered to the upper right, which makes it difficult to play.

This is not for those with no tactical experience. The game will punish you for making mistakes. The controls are hard to master.

Love playing this game. I'm absolutely horrible at it, but it's very fun. Main reason I'm giving it one star is because I cannot save it. Won't save to my phone, for some reason, and won't save to Google plus, since that no longer exists. Would love to be able to play it again, but I really can't if my progress is getting deleted every time I leave the game.

I love the game but I suck at it. But that's not the reason I'm giving it one star there's been no new updates since 2017 and the game feels way too fast pace. like I play easy mode so I can get better at the game but I can't even get a day of research done without something happening.

Tries to cloud save to Google+, which predictably fails, given that it hasn't existed for 2.5 years now. Misregisters the location of your touches so you have to tap sightly above buttons, and you get stuck in one demo level because you can neither shoot or cancel your action. I'm sure it's a great game but it's been abandoned for years and is approaching unsupported obsolescence.

Don't buy. You can't save because their login software is broken and they're too lazy to fix it. Everyone who bought this, like me, deserves a refund until they fix it.
