I just started this game yesterday and after the first gym I went into this dungeon-type alley and tried this moving box puzzle thing. I spent like 15 minutes fidgeting with it(still don't understand the goal) and eventually my character just froze, and I can't move it. All my menus still work, and I would rather not restart my file. Is there a way to go to a previous save? I saw something on the Reddit about changing file names in order to do revert to an old save, could someone explain this in layman's terms? Or is there just some setting to revert that I missed? Thanks in advance for any assistance.
