Dark atmosphere and a darker theme.
Gameplay it's pretty simple, you can only jump and use an action button. There are no attacks that you can perform, but there are quite a lot of deaths, and they don't make you feel good, it's this strange sensation that everybody is fighting for survival and the puzzles are very well design, making me look up ways to go over some obstacles here and there.
The journey is very short and when reaching the end, the puzzling end is also misterious, but what gives this game a strong identity, it's pretty unique and a challenge that you have to be emotionally prepared to endure. It's just beautiful, but as a game it's pretty short. This is quite a goo mix of the video game media and art.
