Just copying over my steam review:

Ghostpia is a wonderful story about learning to cherish your friends despite your world weariness. I just finished this game, and it was an incredible ride. Everything about this game is amazing: the visual presentation, the music, the characters, the writing. There's a lot of heart in the exploration of Sayokos struggle to find her place in the world. She tends to get very negative, but gets quickly pulled out whenever her friends are around. It's very sweet seeing that dynamic evolve over the course of those 5 episodes.
I also really appreciate the great english translation work. The dialogue is definitely my favourite part. The game is in my opinion at its best when the characters' interactions bounce off of each other with their funny remarks and witty observations. Once they get going the scene really starts flowing, and that's both in thanks to the writers having a great grasp on who the characters are and the amazing translation transforming that writing into really enjoyable scenes.

I highly recommend this game. It's a real treat
