This is the sort of game which is genuinely disappointing because it clearly has the potential to be awesome, but seems to fall just short of actually realising that potential thanks to the cumulative effect of its many flaws.
The controls, inventory management, army management, and everything else don't appear to have been improved in the slightest from the original. As much as I'd like to say something redeeming about it, I simply don't see anything that would merit praise. 1/5.
It's an interesting take on the tower defence genre, certainly. Still, it's not too terribly challenging once you figure out what you're doing. I would have given it 4/5, were it not for the obvious bid to drive traffic to another site by removing part of the game's content. So as it stands, 3/5.
