Really good game.
Die several time before understand how to play the game (at first I don't even know how to get rid of the death ziggy, I was looking for the trash bin because of the icon in the machine instruction)
In the end I just use almost all of the ziggy on the oxygen machine and still survive without fixing any hole (I just read how use the tool after I finish the game).
(a little bit unrelated but it would be fun to grab and throw those ziggy into the machine in VR)
