There are too many upgrades in the game, it makes the game a bit confusing. You can't even sell your deployed units, once you put them in the platfoorm you won't have any way to replace them with other units. A little bit time consuming, it's the purpose of a tower defense game though. yeah i don't have enough time to get the hard badge 3/5
I love this game. it's one of the best game I've ever played in my life. The graphics is simple and not that bad. The end is sad and it's one of the reason why I liked it. I would give it a 5/5!
