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.

Sometimes it feels more like one giant ad with some gameplay in between. Having every game end with a video ad consisting of three scantily clad young women dancing is super annoying, too. It's not something you want popping up on your phone when somebody looks to see what you are playing. Turrets seem to prefer focusing on enemies further away, often times leading to low health enemies waltzing by ignored while a full health enemy quite far away gets attacked instead. Sometimes it feels intentional, like the game wants you to fail so you will spend money to purchase upgrades. Some bosses freeze your turrets, so you have to click them repeatedly to break free. The problem is, sometimes while clicking them you risk accidently selling the turret. That is also frustrating, although rare. Giving it one star because of the ads, though. You get ads after doing just about everything. And seriously, can we get some ads without half naked women?
