If you talk to the receptionist, the option comes out but it is not yet implemented

I am not saying there are no preferences, I am saying that the preferences of the characters I created are different, but when changing characters they have the same preferences.

If it is a mistake, then I am having failures in the individualization of my preferences in the characters that I create.

Regarding the preferences of the other characters I have no problem or complaint

Sería una investigación que desbloquea una mesa con tentáculos donde interactúas con el sujeto, con los riesgos biológicos, podría cambiarse para segregar las sustancias que ya existen en el juego a los tentáculos y depende de cuál afectará al sujeto.

It would be an investigation that unlocks a table with tentacles where you interact with the subject, with the biological risks, it could be changed to segregate the substances that already exist in the game to the tentacles and it depends on which one will affect the subject.or so I could see in the game

improving polygons is fine, in fact it would be better if we could also edit it

That's more of a suggestion to the character editor
