excellent!
the monochrome look is a great step outside the other shooter games on the sight and adds a bit of a spacey feel to it. after playing plenty of missions and being on about level 60, I think i can say that there is plenty of money to be had as long as you kill most of the enemies on each level.
The only major thing that bothered me was when the A fighters would fly behind me and do a loop to come back and smash into me.
Great work man.
