That was quite clever! The art is unnerving, the soundtrack is creeping, and the atmosphere is genuinely despairing.
I like the way the endings are laid out. The most natural outcome of a first playthrough is exploring all the room has to offer, which is the easiest run. It forms a natural difficulty curve: try again with fewer hints. By the time I tried my hand at a 0 hint run, I had a good sense of what sort of thoughts the poems were trying to convey, and I managed to snag a key word. It's a great design choice!
Fantastic! Great work!
