As I assume there are already comments praising the innovation of this, I’ll get into other things.
First: Story wise I gather the box was made in a time the Lichqueen didn’t want the Trickster to find the phylactery, but also was in love with him. I guess this is shown in the Safe Room, that contains the Trickster’s statue. I think there should be more rooms hitting on some kind of duality in her thoughts: “I love him, but I hate him.”
Second: some of the rooms don’t play ball. 15 will break entrances, worse is room 10 that will have important coffins missing when rotated and have broken connections. I guess this is… intended?
Third: This zine needs a YouTube link to a tutorial to solve a cube after the adventure.
