I was playing in 0.9.0 and my bad, I didn't read your past comments as I was still having my first playthrough and didn't want anything spoiled.
I'm glad the healing issue with that boss is fixed.
Another thing, is my gallery completed with all the current fights? (still 0.9.0)
I don't know if the middle holes are supposed to be there, so I would like to know if I skipped some encounters (most likely).
I remember there being an enemy that interacts with you when you sleep but I don't think I've fought it.
Also, as you can see from the image, the duo fight against the mermaids is missing. Maybe it was fixed in the latest updates, but the duo only shows in the defeat scenes.
