Ghost Song

Ghost Song is a love letter to metroidvania genre with a huge map, so big that even the portion that can be immediately visited could almost represent a complete game. The game features an excellent graphic design, albeit with improvable animations, and an interesting story to follow despite starting with a little delay. The soulslike component makes things as hard as expected, and while it might annoy players who don't like repeating the same section again and again, it's part of the game. Definitely recommended for those who love exploration, too bad for the limited support for keyboard / mouse combo.
