Absolutely incredible game, although a little short. Graphics, sound design, and animations are out of this world. I have never seen a game as polished as this one, and the fact that a single person made this blows my mind.
If you read through some of the creator's responses, it's clear that he's extremely skilled at all aspects of game design, and very passionate about this game. The game has not been abandoned although it may be a while till Chapter 2 comes out (based on his responses). That being said, the game only takes a little over an hour to complete, but that hour is one of the best I've ever had in videogame history.
P.S. I can see the inspiration from SOMA (my favorite game of all time), and I love it!
