After the credits, there's a voice-only therapy session given to Simon by the Gini therapist.
Later, there are a few texts suggesting some fun things to try in the game. One of the things says that there are three different therapy sessions that you can see after the credits, and that you have to play differently to see each one.
Does anyone know what that means? I assume it can be one of two things - either the three alternative ways you can handle the swampling on the space ship, or the different ways you can handle the long dialog puzzle in the end.
MaGtRo's walkthrough doesn't mention anything about it.
On another subject, I saw this on the walkthrough:
Change to another character is done by left mouse click on the character switch icon seen at bottom right of the screen.
I assume it's a mistake?
