This series of underappreciated puzzle games just gets better and better. The Room 4 is another entry into the puzzle-box, pseudo-point and click adventure games, but this time tasks the player with exploring different rooms of a mansion to uncover its secrets. Because the whole game takes place inside this framework, it feels way more cohesive, and I loved swapping between rooms to get solutions, rather than having all of the answers stuck in one room. Like most of the series, it's not too much of a challenge to get through, and if there is ever a moment you get stuck, an intelligently balanced and fair hint system can point you in the right direction. My only gripe is I was hoping to see more room movement like in the Room Three, with double-floored environments and secrets/hidden rooms. While I appreciate the one ending, I really wanted some other reason to explore the house. Cannot wait for the eventual return to this franchise.
