Tip to anyone playing this game: use the ARROW KEYS (not WASD) to move around.
I found 2 of the gears, but I wasn't really able to tell what was going on. I think it was hard because every screen looked almost identical. Some visual variety might have helped with communicating what was happening. I think every room is supposed to represent a different year? I couldn't quite tell. Anyway, it's a cool idea. With some more polishing, I think it can be even better. Keep it up!
