There is some potential in this one.
There is a good amount of variety in the individual repair steps, I liked this. The leg stuff with the bars was pretty intuitive.
After the bar stuff, I got stuck. You couldn't just figure out stuff on your own. You need the manual, which I hopefully found. This info should definitely be included in the game. But it kinda got it own charm, like the in Metal Gear Solid, where the code is at the back of the CD. But this still needs some sort of hint IMO.
More player feedback would also be better whenever a green light lit, maybe a success ping sound. Also when the repair is done. Could have been a glow on the helmet or something. I assume this is due to no time left and all.
