How do I change characters in The Ruins of Sarudnahk?
Solution 1:
No, there is no option to change characters dynamically, as stated on Gamefaqs forums:
I'm pretty sure there's no way to change again.
and Steam forums:
I don't think you can change it once you have chosen.
[...]
Yeah, I just restarted the game.
However, Steam user Link2434 said:
If you chose Kaeris, don't worry; you'll later be able to come back as Clink
So surely no option to change directly, but "maybe" another chance later in the game.
