Chapter 9 Globe: The book shows symbols (single dash, double dash, tripple dash and a dot) for each planet. You need to set the highlighted ones on each planet to green.

Anyone know in Chapter 9 : I don't get the Mask Icon to put into the chair. I only get the globe? I think part of it is because it gives you all the items automatically in your bag.. Can anyone help..

lol, I dropped a comment and found a solution

Hi! For some reason the steam combination in chapter 6 (5:33) does not work for me

Does someone have any idea?

大家好，這個遊戲，關乎於1984左右發生的太空教課書裡，資料豐富，又不失考古，能理解的人大部份為1980前出生的人，經過我的努力，終於解開所有謎團，但對於下一代而言，事實的真相為何？讓我們來期待。

no mask hologram appears in chap 9, only the sphere. Like a few other bugs in the game, it seems you can move forward without it just ignore the stuff you can't do i guess

+RESPECT thank u

As a quick update to the last vid. Instead of placing the helmet and having it unlock the map sphere, the MC automatically puts it on 'after' the map puzzle instead.
Oh, just as a quick fyi. I know things are kind of damaged and whatnot, but it kinda spoiles the reality of the technology when you see a hole in the glass next to your head when flying in space.
Awesome game, can't wait til the next one.

@aresworld123 It's just a red herring. It reduces the chance of you picking the right key first time.

whats the worn out key for
