Dynamic SFX were quite cool. For me, could use a little light bgm. The real challenge I suppose is the risk vs. reward component of pushing your reactor toward 0% stability to maximize production during high demand, and letting it recover during periods of low demand - but there's not really any pressure or incentive to make you do this. A daily timer, some sort of quota system... A reason to have money at all, would be nice. I like what you did with the dynamic aspects of the visuals in particular, in general they have quite a clean look.
