There doesn't seem to be an option to invite a Steam friend prior to starting the actual demo so I just end up starting it by myself.

Hey, I was playing the game and on chapter II, the first puzzle as soon as you go down with the elevator, the lights won't light up when I interact with them and it won't let me progress, tried reviewing the files but everything seemed fine, also tried uninstalling and installing the game again but still didn't work with any of the characters. I was playing with the playstation dualshock 4 and figured out for some reason it wouldn't let me properly interact with things, tried keyboard and it worked...

Is there any way to get it?

Doesn't make a good impression for the possible difficulty, extremely easy and way too short.

ME AND MY PARTNER CANNOT DISCERN WHAT THIS MEANS There is a puzzle in chapter 3 where you have to block certain symbols from reaching the orb, and on the only youtube walkthrough for this game the guy just knows somehow what ones to do and what ones not to. What is the logic here? It's driving me insane, there's no hint anywhere....
