Hi! I've been enjoying the game's atmosphere, but I've been stuck in Subsurface for a couple hours now. I've found a variety of secrets such as a short phrase which I then used to obtain longer phrases to bring back to the one creature with the light, and I managed to make a new scene occur after this which led to a buncha worms and orbs sprouting out all over the place, but it's not clear if this has had any other effect? I also have no idea what to do with the memory items. I've found the dark room with the five little glowy, floaty guys and the other secret with the doorway covered by what seems to be worms? I've scanned the "perimeter" of the main chunk of land and I've found 3 entrances (including the one underneath the large figure that I'm assuming is Tiamat). I feel like there's a wall somewhere I've not thought to walk through? It's a bit difficult to tell what I'm missing.
Edit: Oh! I see. I found the annihilation ending!
