Explore five interconnected worlds shaped after the five platonic solids, each with its own unique theme and gimmick. You will need to deeply understand how each part fits together in order to progress. Not just as a series of linear challenges, but ones you must actively seek out and discover.
Gather clues along the way. There is no inventory; information is the only key you'll need. Solve challenging puzzles. Learn how each mechanism functions. Blindly guessing is not an option. No two puzzles are the same.
