The Room Series 10/10
These are the first few games that Fireproof Games have released at the moment; and if that's their first series, I can't wait to see what they've got lined up. The soundtrack was not much, just some eerie noises, but I didn't think it needed a soundtrack anyway. The story is told very abstractly, so it does require a bit of thinking to understand. The gameplay is absolutely stellar: it's an observational puzzle game, so prepare for really specific viewing angles and awesome complex puzzle-solving. Finally, the environments and objects they use are really cool, and very heavily influenced by the Occult; there are complex safes, intricate designs and clever custom Tarot cards. Overall, a great series and a true masterpiece of a puzzle series.
P.S. If you play through in order, you can totally see their evolution and progression of gameplay over time.
