On paper Ghost Song is another in a growing list of reasonably enjoyable metroidvanias that doesn't do much to drive the genre forward in a meaningful way. However what stood out to me is the mood. Even on this dead world full of dangerous creatures there's this uncanny calmness to the atmosphere. This is portrayed perfectly through the beautifully gentle voice acting of the player character. The world is full of deep lore and shrouded in mystery. Our protagonist has no memories and we don't even know if she's human, an artificial intelligence, or something else. Just that she is inherently a caring and considerate being that feels the need to help others. I'll stop there as to avoid spoilers but the interesting world, tone, and story give extra weight to what is otherwise a fun but unspectacular game.
