Okay general comments first. I really enjoyed the OST. Super varied and interesting.
If I had one nitpick is definitely that some I feel lack movement at some point, so some tracks should either finish a bit earlier, or introduce new things to keep it fresh. The most notable example of that is definitely Cosmocats.
In saying that in doesn't deter at all from the great ideas and the really good execution. Also mixing and mastering are flawless so it's really a comforting and interesting listening experience you got us there!
Treacherous was the highlight for me, but it's mostly because I love drama so much xD
Quips and Quirks was exactly what the title suggests, really nice :)
Overall it's one really really good submission! Thank you for sharing!
