While working on the interior design of the Heptomusee building, we added a toilet space. It is just an objet that has no bearing on the game’s progression.
We designed a pictogram to be displayed at the entrance. There are so many pictograms of this type, it’s difficult to make one that’s unique. The following is one idea, but it looks like something from the Olympics.

The image below shows this not painted on the wall in blue and red, but actually placed like an objet.

There is no consideration of universal design at all.
