What an amazing game. I was definitely hooked. I would wish there had been some more puzzles that don't involve only killing things (the adventurer in me), but the atmosphere, design and ideas are superb.
Am definitely going to recommend it, like others have to me!

However, there are a few things I'm not sure I understood:

1. At a certain point, the first sister (Sister death?) dies (willingly). In her main chamber, there's an option to interact with her tree, but I tried reviving it, and tried other stuff - and nothing happened. Is it possible to do something in there?

2. Characters mention a few times throughout the game that I need to choose the correct sister. Is this just a metaphor, portraying the fact that every sister will create another form of life up there - or is there really one "true" sister, game-wise?

3. I've never used the vampire glyph. I mean, I tried to, and ended up killing a sister without getting anything, so I reloaded my game. Does that give anything?

4. I've tried freeing the right-most, upper-most sister (the one that calls you in the beginning, and that is the hardest to reach to). She seemed to be a pretty important sister. I've failed however, not having enough color, and switched to another - but while feeding her, she kept mentioning "god send", and that "god send is gone...". Is that the first sister? Who's god send?

5. Does killing a sister (with her poisonous colors) help in any way?

I think that's it for now.

Is there a sequel being planned? Or some extension?

Thanks!!

1- You can try and draw the breakthrough glyph on the Nameless Sister tree

2- There is no true sister, gamewise. That is up to you to decide who is your true sister.

3- Nope, it doesn't give anything. In the original Russian version it was used for something else. They changed it, but they never got it to work correctly.

4- Her name is Ole , and God Send.... god send ... god send.... (That part is never explained)

5- Nope, but you can do it if you feel like it.

Thanks And no need to get upset!

Not upset, but who could someone forget the name of Ole.

I mean we are talking about Ole here.

IIRC, Godsend is the sparkling Sister you chase around the Surface. If you listen to her, she will say something like "My wings, where have they gone?" and other such clues. Who she really is depends entirely on who your "Godsend" is. Pure theory

About Godsend:

1 - Ole mentions that she had wings and fell from above, crying

2 - Yuna has purple wings, mentions that she has been to the limit above, and that she doesn't want to go there again as it's just as bleak as this one.

Based on that, my guess is Yuna is Godsend.
