105 Puzzle Demo Completion Tracker
Track identified Demo rooms and return to the next unfinished idea.
Save progress you can recognize
The 105 stable IDs keep your notes attached when an unverified record gains a real room description. A title can improve without changing its URL or erasing your checked state. Mark a record only after its starting features match your room.
Mapped worlds and pending records
World totals follow the current registry mapping. Newly matched Part 2 rooms appear in their observed world while their original stable IDs remain unchanged. The unassigned Part 2 group shrinks as those matches are established.
Back up before moving browsers
Solved flags, notes and preferences are stored in this browser. Export JSON for a backup. Import validates known IDs and the data format before offering merge or replacement; merging keeps your current note when both backups contain one. Website progress is separate from Steam save carry-over.
