Puzzle design... Lucas, you are absolutely evil, and I mean that in the best possible way. This game is hurting my head, and I love it. Part of me wants to start over to review the mechanics as they come up again in case that's why I can't figure out what to do next. Part of me is terrified that I'll forget how I freed the orange key, and spend an hour figuring it out again
Seriously, top notch work everyone!
