Incredible linguistics based interaction with the world, reminiscent of late game Fez which I regard highly. Context, observation, imagination all working together. Very clean user experience with no need for external programs to solve the world around you BUT I wish it were fully diegetic, getting rid of "validating glyphs" through your book but I can see how it'd be very hostile to many people interested in this. Still very enjoyable and I hope it sparks the creation of more games like this.
