Just finished it! Great job on the art. I liked the minigames. Rearranging the letters and hangman. I wish there were more of those.
At the same time, I wish the puzzles were a bit more involved with the point and click stuff. You just entered a room, and clicked on everything until the next dialogue sequence started.
The characters also just walk into an empty room with weird paint, and just kind of... assume, that there are traps that are going to kill them? It wasn't very clear how or why they couldn't just move. The only supernatural thing the Ghost ever does is lock doors and talk from nowhere... which could just as easily be elaborate microphones and gizmos.
The story also suffers from the fact that there are numerous GLASS windows in the backgrounds of various rooms... and the characters have bricks and scalpels and maces... but instead they ignore those and willingly climb into Iron Maidens and break their own fingers?
Maybe I'm over thinking this :)
PS: The scene where they had to break their own finger made me genuinely uncomfortable. Good job!
