The game is excellent, dark, atmospheric, albeit minimalistic: the color design, environments, and sound are all top-notch. The puzzles are built on interaction with the environment; they're not exactly challenging, but even with minimal options, they challenge your brain. The secret ending stands out; in my humble opinion, I never would have figured it out on my own. Furthermore, it requires secrets, and finding them requires more than just paying attention; you actually have to explore the locations. The game almost forcefully instills a certain curiosity in you: "You can see exactly where you need to go, but if you get distracted, go in the opposite direction."

A definite plus is that the game doesn't rush you anywhere; it moves at its own measured pace, giving you the feeling that you can take your time and do everything at your own pace. The final part of the game, filled with a unique "action," is all the more unexpected.

Overall, a 10. *For some reason, I couldn't move the sliders near the rating criteria.
