This game has a lot of good mechanics that could make it really good, unfortunately it's just a little too obscure to make it worthwhile. I found myself guessing for some of the solutions, and just going with trial and error on others. The Grimoire is just too vague and the solutions too subtle to make it feel engaging and worthwhile. That being said, this style could be a lot more enjoyable with a more straightforward solution, or a better indicator that you are doing the right thing. It took me a little over an hour to fully complete this game, but I cut a lot of it out for time.
