The only reason why people are hating on this game is because they don't understand that this is a side game. Don't worry Wix, just ignore them! (also, I think this game is still pretty great although it's a side game..)
I absolutely love this series, but this one is definitely out of place. It went from a great shooter to this defense type of game. It's still a good game, but he cannot compete against the previous two games. I'll give it a 3/5.
It's super addicting, but doesn't really need the switching feature. It smarter to just upgrade all of them at once when you have the money. It would be cool if you could add more progression to it, other than bigger boxes and another things like that. Maybe more characters? 3/5.
