Thanks for playing. All the glyphs in the wall that are partial solutions have a unique combination. In case of the solution for the exit door, there are two parts.
Other people complains about it's hard to distinguish the frame and the glyphs, so it's something that definetly requires a rework to help the player deduce what I commented

Yeah I struggled with figuring out what is part of the glyph, too with the first code but once I had understood that it worked well. It was just hard sometimes to find exactly the right position to see the symbols correctly. But figuring that out was kinda part of the learning curve so I think it's fine.
