D-Don't worry, that was the only RPG game I could finish since I watched too many playthroughs of the game. I finished Mermaid Swamp, but I'm aiming for all endings. Can't play Ib, cause it stops working at the storybook.
At the story book part, just click on put book back in, and don't watch the movie. The key for the door will "fall out" of the book. Then you don't watch the storybook, and your game doesn't crash. =3=
Idk if you fixed it yet, but that's what I had to do, so I thought I'd help. c:
