I can't fully criticize the game because I seem to be stuck with a buggy ending where the protagonist dies no matter what I do.
Still, I liked it a lot, the terror of the game felt authentic and I had to restart the game in windowed mode because of how intense several moments were. Otherwise, the backstory is interesting and the puzzles felt tedious but they are easy so it's not that big of a deal.
Good game, thanks for translating it to spanish too!
