This game is nothing short of incredible. It features a multitude of incredible pieces to make up a fantastic game: soulful music, beautiful graphics, unique gameplay, and an endlessly interesting narrator. The sheer amount of effort put into this game is plainly visible, and I cannot recommend it enough. I've put 8 hours into this game for a single playthrough, and I will certainly be going back to play it again. I've also purchased the soundtrack (for all Supergiant Games' works, actually), and I truly enjoy listening to it.
I played this game after being introduced to the studio by their second game, Transistor, and I will certainly be playing their other two works as well. I am confident that whatever they create will be worth my time to play it.
I especially enjoyed being able to vocalize my thoughts on the game as it progressed. I think it would have been a little bit of a different experience for me personally if I hadn't recorded it.
