I don't want to necro any old threads, but how has this not been addressed by now? Overwhelmingly positive is mind-boggling to me with a system like this..
Playing with m/kb is either uncomfortable or straight up so annoying that it's unplayable.

Within minutes of playing, it became apparent that the escape key is used a lot if you don't want to move your mouse all across the screen to push the corresponding buttons, and it's the same with the enter key.

Well, rebinding would definitely sort this, except for when it's done like in this game. I'm shaking my head so much while writing all of this, I'm amazed.. So can't rebind anything for the mouse, m4 and m5 buttons are not used and are left useless in this game. This was my first preference for esc/enter.

Rebinding esc to tab, and enter to space seemed like a nice setup, except that the developers have their own keybindings for the menu that can't be changed:

Tab now opens the shopping list when I want to close (or go back on) the computer, and space is selling the part I'm trying to add from inventory to the shopping list.

I could live with having to close the computer by moving the mouse across the screen, but adding parts from the inventory to the shopping list with the same tactic is near impossible, as the mouse will highlight any other part it hovers above along the way.
