Foldsite

Foldsite is a first-person architectural puzzle inside a compact paper-like structure. Read the section drawing, rotate a hinged panel to open the indicated lane, walk through, and stamp the corresponding plate. Three sections build a complete route to the exit; an incorrect lane remains blocked or cannot be stamped. Shift requests mouse lock, WASD moves, and E folds panels or touches plates. The current section and panel positions are kept locally so a session can be resumed. The game runs entirely in its extension page, without website access, analytics, accounts, or network use.
