3 stars: The game is addictive and fun to play, at first... Once you get halfway, your towers will have no effect on enemies unless you do massive upgrades. That's the fatal flaw, the upgrades are unethically expensive. Developer... shame on you for making this decision. I'm now stuck on the final level, final wave on easy mode. I will probably uninstall because it will take months to get enough gold to upgrade.
3 stars: The game starts off pretty good, it's not really that interesting when compared to other tower defense games. It also has a problem where in later levels the towers don't feel powerful enough. The only good things I can say are that the graphics are decent and you can play the game entirely without an internet connection.
5 stars: I'm an old school tower defense guy, and this is my kinda TD! Loving it so far, though it's becoming harder and harder as the levels progress. One minor quibble: I sure wish I could hear the sound fx without being forced to hear the music. Overall, one of my favorites. UPDATE: THIS GAME NEEDS A SEQUEL OR MORE LEVELS PRONTO! Seriously, need more.
5 stars: Really interesting game. But it's hard to earn money for upgrades if you're already on the ice part, rather, the upgrades a just way too expensive.
3 stars: This game is a lot of fun. I want to start over but the game won't allow. Deleted the game data play games data playstore data etc and it reloads where I left off when I reinstall. Deleting the game for good.
