W/o Context: LOVEEED the piano used here. The breakbeat's tone also feels good and balanced when it comes in. The simpler parts would support puzzle-solving gameplay well. I kind of wish I could hear more forefront melody lines aside from arpeggios. However, if you made that decision to keep the songs non-intrusive, then it's a solid choice. Curious what the heavier sections are for, though.
W/ Context: Ah, so there are chase sequences! The story has a nice setup.
