should have an undo button that undoes the last movement or waiting. puzzle games without undo buttons are just tedious

I really enjoyed. Very fantastic idea! Room X.0 Sometimes the bridge tiles disappear even if there is a person on the second switch from the left. Or it's a complicated mechanism, so maybe I just don't understand it properly. https://steamcommunity.com/sharedfiles/filedetails/?id=2521803572 After defeating room X.3, the game said "End of demo" and all progress was reset. https://steamcommunity.com/sharedfiles/filedetails/?id=2521803784...
