Nice, but too easy.
I have to say i found the working space is a bit messy, with all the movable components mixed among the fixed ones; moreover the playing window is too big.
Very nice game, great learning/diffulty curve. Maybe a bit repetitive. Nice plot (not very original though) and atmosphere. 5/5
I think it needs some hotkeys for the weapons, like 1-2-3-4 etc.
