They will be available in the future, 1 by 1 they will lead the player to a criptic zone but no spoilers for now stay tuned and thank you a lot for playing!
are any of the vents available yet? I noticed you left this a month ago, so I wanted to make sure before spending too much time on it. Also, is there a version on patreon I can download? the demo has a weird visual bug where I can't see the walls at most angles
