Very cool and mysterious game! I think part of the appeal was just trying to figure out what was going to affect what. I could see a possible desire a player might have to color code or have some sort of visible signal to make it more apparent what switches are attached to, or if there are partial configurations complete, but I could also see how leaving it vague keeps it more interesting. The controls are perfect--of course driving in reverse takes some getting-used-to, but everything feels right. I like the final goal too :-D Great work!
