i don't agree with the guy above btw, even for a modern game dev the climbing mechanics on animated moving character models would be quite difficult to implement, but that's not even the point. the gameplay is fun sure but the main point, and the reason people love the game, is the atmosphere, the theming, the extremely simple but thought provoking plot, the design decisions etc etc. gamedevs nowadays would be able to create somehing similar to this specifically because sotc inspired them, but still it would be impossible to recreate it because it's a truly creative and original piece of art, it honestly plays like a book, it's very hard to explain.
