Very cinematic! I think you made good use of those thin, fragile strings in the 3rd track, definitely conveys the girl’s control of her “world” becoming more tenuous and strained. A sadness permeates the whole soundtrack, adding to that feeling of being lost in your own world, almost like Mei is becoming a stranger there. Looove the reversed piano in Creatures mixed in with the unreversed, very underrated combo! Overall a nice set of ambient tracks, these would work great as BGM for the game you described. One critique I have is that at times the mix felt a bit off in terms of volume, I especially noticed in the 1st track with that second theme. I think the theme is definitely contrasting enough to stand out without being made so much louder. Otherwise, very nice work here!
