The game play is really fun in the beginning but lots of ads. I paid to remove them and annoyed it at first when you can progress pretty quickly but once you get up into the higher levels, (into the levels above about 5 anyway) it takes so long to move up it's not really worth it anymore. I've been working to get from level 12 to 13 for about a month now. Also each level is just a repeat of the same aliens just with more with more hit points. Pretty redundant.

Fun time waster, ads are by choice. Recent update actually made it better. But it just takes forever to get anywhere. The more you play the more you need to play to advance. Edit: it's been 1 year since I wrote that review and then uninstalled it. And I couldn't remember why I did. Everything was great. Then I started the frozen side and remembered how slow and tedious the game becomes. It's like the frozen side was written by a different person than the warm side. Uninstalling, again.

Recently, I got the winter area base upgrade, and I am now running into a delivery worker bug. They just randomly teleport back to the base, and if they collected anything from you, it gets deleted. It is annoying if you've spent time on a particular enemy and they collect it just for the loot to be deleted... Would appreciate it if you could find the cause of them getting randomly reset.
