I wanted to let you know I think you're onto something really cool with your game. 

Also a couple notes, I was hoping you could put out the controls in some place easy to find, all i know is shift-click, f5, f9. Is there a way to quickly duplicate an items settings, like the guns or motors? Some items i have no idea what they do to, like the mechanical heart shaped thing that goes in the mech auxillary slot and i assume the other item is a battery of some sort. Also was hoping you could look at improving saves, as loading normally corrupts the game, sometimes visual errors, or breaking the world map (sometimes completely sometimes partially by removing specific zones), and duplicating audio.
