Worth every single cent!

TLDR: Recommend the game for the overall experience, though it is lacking a bit in the difficulty.

This game had a great atmosphere and storytelling, with interesting themes throughout the different rooms, that contributed in a great experience overall. I had a good time going through the rooms and solving the mystery in front of me.
However this was probably the easiest game of the series, which I feel is a downgrade from "The Room 3" the best one in the series. Although there is an effort to use multiple room mechanics to complicate things, it was always clear what the next step should be without using any hints. As a result the game seemed to be rather short.
