How do I reset a completed puzzle?
I solved a puzzle on accident in The Looker while messing around and scribbling at random. Can I reset the puzzle to try solving it the intended way?
If you haven't quit and saved yet you can try force closing the game. Otherwise it seems the only way to reset a completed puzzle is to erase your save file and start the game over.
Return to the tunnel where you started the game and keep walking until you reach a door. There will be a panel to your right you can solve to delete your save data.
