I like the platforming, it's like the old Tomb Raider games. The second track in the desert after a particular mission makes exploration much more enjoyable. I love the music variety. There are tracks with similar vibes as Nier Replicant that combined with others of different styles make it a very special OST. In the train station level, which is full of dangerous enemies and tight jumps, you are listening to some chill piano in the background. That's pretty cool, like the music in the White Palace (Hollow Knight)
What amazes me the most is how many good design decisions are in the game considering it's Shift Up's first. From environmental storytelling (no lengthy cutscenes) to pacing, fun mini-games, clean UI, etc. Compare that to the Ubisoft template with a million icons on screen and exploration for dummies. This one embarrasses a few veteran devs/studios.
