Lack of IR pointer is an issue. The controls could have been better, and lacking the controls the game seems a bit redundant.
I bought it, and it wasn't what I thought it would be (I'm not referring to the controls which I understood when I bought the game). The slow start of the game killed the excitement somewhat, and as I got deeper in I realized it wasn't so much a strategy game as an rpg.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
