Really nice game! Liked the ambience a lot, got me immersed.I liked a lot the main gameplay of digging out the artifacts with precision, and how interactive it was, very much in theme with playing as an archeologist! The visuals and audio also very well contribute to the feeling of unease in a very strange place.
I liked each feature being explained along the dialogues, very good in-game tutorial experience.
One thing I did not get was if you can actually run to the elevator in the first scene, because first I did not know the inhaler existed as everything went down a bit too fast, then when I noticed it it seems I couldn't reach the elevator. But I think it's fine for gameplay purposes.
Also, I did not really found running that useful in general in the game (in the first section, even without running you can outrun the darkness by a lot, stopped only by the dead-end of the cave).
In conclusion, an overall good immersive experience! Kinda wished it lasted more, haha!
