Ghost Song is an okay Metroidvania with a Soulsborne death and bonfire mechanic. The platforming is fine, the combat is shallow but serviceable, and the story is almost nonexistant.

True to Metroid, the map opens up as you collect new weapons or abilities like double jump, wall jump, rockets, etc. Your goal is to collect engine parts for a ship you won't even escape the dangerous moon on. The crew of this ship will have multiple boring conversations with you revealing the smallest fractions of a personality per person. If you work annoyingly hard, or be smarter than me and just find the quadruple jump before attempting it, you can find a secret location that changes very little of the ending. When the credits roll, you'll sigh and move on to some other game.

Ghost Song is just really forgettable. Its monotony and emptiness is intentional which makes me angry knowing they liked it feeling like a void. To make this void worse, there aren't enough fast travel locations, so if you think you forgot something (good luck with the map, where you cannot zoom in very far and no location is named unless you are currently in it) somewhere, you're in for a trek that feels needlessly arduous.

The combat is pretty easy, with very few exceptions, and the punishment for dying isn't so bad. A bit of semi-permanent damage is done, capping your health a few percents until you go to one of those rare fast travel locations and repair it for a very cheap price. Though it only happened once, I believe there is a punishment for dying before collecting your remains, and I believe that's you losing a Suit Level. I'm not certain about this, however, and I do not really care (and neither should you).

Not worth your money. Needed more time and energy.
