What a unique concept and it ticks so many boxes that I wasn't even aware of existing in my mind and really needing to be ticked. Unfortunately, it has some major downsides. Some puzzles can be done only by bruteforcing them as far as I understand (4 invisible triggers in a location), immersion and mood are completely destroyed in a couple of places by out-of-place and anachronistic shitposts (skeletons and David Lynch), and I feel like some of the endgame levels don't do enough for the story and it feels unfinished. On the other hand, going through an unfinished game in a game that feels unfinished absolutely works on a metalevel.
I just like the idea so much that I wish there was more to this.
