Forenote: I played this entry in English.
Even though the game is fairly short, I only had the stomach to reach two different endings. The writing is quite gruesome, with violent imagery, which considering the events happening around the release of the game made it very hard to read (personally) - even if they are probably not related.
The interactivity and choices available, as well as the responses from those choices, are pretty confusing, which makes total sense since this is supposed to be some sort of nightmare. The branching also seemed quite complex, with paths seemingly looping back.
Pretty impressive for something made (originally in Spanish) in 4h!
