I think the key's creation location should be more sensitive.
I just couldn't find the key at the maze tile set level.
The map was rather small.
It wasn't the level to create a travel talisman instead of no way out.
I kept walking around, but I couldn't find the key.
Maybe the key was created, but I think it was stuck in the wall or overlapped with another object.
Previously, I spent a long time searching for keys on the first floor and found them stuck in a wooden board where the bed was blocked by wooden boards.
