[Note: spoilers!]
You were right: the game is unplayable on itchio because of the inability to scroll on itchio.
However, I regret to say this isn't a very fun twine game. There's interactivity, yes, but it seems saying "yes" or "no" doesn't affect the game at all. If you say "yes" or "no" to whatever, the game changes for a line or two before going back to the story. There's nothing wrong with that, but I'm sorry to say this game isn't very interesting. It's basically a very long piece of exposition, where Corin thinks he's going to die, and then there's suddenly hope for him because...well, I'm not sure actually, because the solution is something I still don't fully understand.
