Aww thank you so much <3 I'm so glad you're enjoying it! Replacing yume 2kki is incredibly high praise wow.
Also, there are notebook esque items you can find to keep track of the lore! There's an item in Oracle Machine world (red/pink area) that records whispering monolith excerpts, and there's a similar item for recording lore in the Sunless Garden (green area.) I'm planning to add more of these for the other worlds as well :p
