Oh hi SteamGAF! Just got through The Room Two (yes, I raffled off a game on my birthday and hadn't played it yet myself, wanna fight about it?) and here are some quick impressions:
The story: Without spoiling too much from the first Room, you're on the trail of a professor, going through a series of dimensional spaces that play out like puzzle rooms. There are bits of lore here and there, which apparently get fully explained in The Room Three (not yet on PC,) but it plays second fiddle to the puzzles. So feel free to try and immerse yourself into the "what and why" of the rooms, or just enjoy some good puzzlin'.
The ending is left a bit ambiguous, but it does feel like an ending. However, the existence of a Room Three tells me things might not be as they seem.
The graphics: For the most part, terrific. Hard to believe it's a mobile port with this quality. There were some bits that were too dark, making finding the next piece difficult, and a couple of sections of shadows so jagged you could cut your finger on them, but overall it's a treat.
The sound and music: Minimalist, but it works. The scrape of a ball bearing in a track. The click of a dial. Then suddenly, the violin music swells to reveal the next section. It keeps you tense, even though there's nothing too terribly scary happening.
The puzzles and gameplay: Great from start to finish. You can turn hints on or off, depending on your puzzlin' skills (I turned them off and still didn't have a tough time. Not bragging, just saying there's nothing overly complex.) Sometimes the combination of camera and mouse is fiddly - there was one section where I had to turn a slider along a circular track and it didn't want to go all the way until I adjusted the camera - but in general the interface feels good. I will say, though, since there's no good section to put this, that it didn't feel as wondrous or magical as the first Room. The first game had more of a singular focus, and items within items within items. This one had jumps between disconnected sections (which, yes, does suit what story there is) so instead of feeling like you're getting to the heart of something, it feels like you're just spinning in circles.
The length: My Steam profile says 3.8 hours. You're here for a good time, not a long time.
The verdict: While not as exciting as The Room, it's a worthy successor and worthy of your time and money. Now bring on The Room Three!
