This game has a beautiful yet grim story.
I'm usually into open world or action genre and have no patience for Puzzle/Platform games, but the loneliness I felt by playing this game was so unique and attracting that I couldn't play anything else till I finished the game; And the soundtrack was amazing too.
Also the puzzles are really easy.
If you enjoyed this game, [Lifeless Moon] (2020) is a spiritual successor to this title
Edit: Lifeless Moon is set to be released in 2022 (I just hope there are no further delays)
