Interesting point-and-click style game. Some thoughts:
- The puzzles didn't require much thinking, you just do what it tells you in the book... some more stuff to figure out would have been nice.
- I don't understand the plot significance of the "unlock the door" ending. You just leave without completing the ritual, I guess? I thought it would be a step to completing the ritual, but it just exits the game.
- If the beast comes on the nineteenth year after the last successful ritual, I wouldn't describe that as "every nineteen years", especially if they're trying the ritual every fifteen years. That wording confused me.
- I appreciated that the art for the ritual reflected your progress even in the "stepped back" view and it wasn't just a static image. Often point-and-click games don't show your progress in other views like that, so I liked that attention to detail.
