I will admit its a decent game, but that energy system just ruins it completely. You had the makings of a brilliant game but then spoiled it, not to mention those stupid red gems. -.-; this game is a pay to win kind of game... those never last very long
I love this game and its unique TD elements although as a lot of other people have said difficulty would be appreciated. But that is the only flaw I have currently found... the main menu is just too fun :D
