Really was looking forward to try this game but sadly after 5 minutes of clicking I was too stuck... Perhaps some object outlines on mouseover would help. Overall cool visuals and an unusual idea. I hope you polish it some day!
I've added an indicator spotlight to the mech:
Green: Default.
White: Hovering over something clickable.
Red: (after clicking) Requirement not met yet, e.g. previous parts not installed yet.
