Sorry I've been away for so long, but I have been playing the game a lot (unedited screenshot: )
I beat the final DLC boss, and also the hidden boss that leads to the bonus ending. But I still have some questions.
1. How to get the rest of the plushes? I can see that there are still more places in the collector's house.
2. In the DLC sound test, there is another "Always" song, where does that play and how do I get to it?
3. I also forgot how to get back to the mountain where I can access the Sky Abyss, any hints to do that?
4. Does any other dialogue or anything change in any site after you beat the DLC boss?
