Addicting, but difficult
I like this game enough to give it a 7, but I thought there were a few problems when it came to difficulty.
first off, every 5 levels it saves. now this wouldn't be a problem normally but considering the difficulty curve, it is. Because regardless of which level the difficulty goes "so easy the dead can do it" to "Oh god Kill me now"
which some guy out of left field is very happy to do.
It looks nice, the ace features are a plus, there's good variety in the missions, but the difficulty and saving abilities quickly just suck all the fun out of the game.
