Just like with the other previous games from the series you also have to solve puzzles with the power of explaining things to your partner as they can't see what you can see. This one is just longer and harder. We had a game breaking bug with one of the puzzles but it thankfully only happened on 1 of 3 PCs we played it on so we could finish it anyways, but something so mayor shouldn't have happened in the first place.

Works fine on Linux with Proton (Proton 5.0-2).

This game needs quite alot of brain usage, which makes it quite interesting and quite challenging.
