Hi! Thanks for the love, we're so glad you're enjoying Obscura!
The ending guide has been updated already. If your file is labelled for version 2.1 then all the new info is in there (I just downloaded the file for myself to be sure).
hello! i was also browing the Steam Community Hub for the updated guide but i think something may be broken. i can see other parts of the Community Hub for Obscura (as it also requires Adult Content to be enabled) but specifically just the guides section is empty. it seems like maybe this is affecting newer/recently updated games? i cross checked with a few other 18+ games. it would be very helpful and appreciated if the updated guide could be listed under itch downloads as a workaround ^^
