The Room series is a very consistent series, with titles that all have the same qualities and weaknesses. These games are basically like shape-sorter toys pretending to be puzzle games. But it comes with an excellent dark art direction, very creative visuals and cool animations that it's still worth playing if you're into that gothic horror vibe. This 4th episode takes place entirely inside a mansion, with each room having a specific theme. It's pretty cool, I especially like the Japanese themed room.
Just don't expect a real puzzle game a la Myst, as all the puzzles can be solved by pressing buttons and inserting objects into the right holes. There isn't really any moments in which you really have to think about the solution. Most of the time if I got stuck, it was because I didn't know what part of the mechanism could be interacted with.
