The first half and the ending are pretty good. "Slow, grayscale, underground" are adjectives associated with levels that either go heavy on the emotions (e.g. Lonely Travel), or have an overwhelming, intimidating atmosphere (e.g. Cimmerian Shade's slow parts). Instead of those however, this has a feeling that I can't really describe as anything other than "jazz". Like, this is the visual equivalent of the song's genre. It's not the anxiety of a Minecraft cave, rather it's more like an underground lounge where you'd hang out with friends. The gameplay restrictions help this to a degree as well, no spikes=less threatening.

Then there's the wave and robot, and listen, I get it. This is supposed to be intentionally infuriating to play, so in theory this sort of sarcastic anti-horror would fit well with that, but it ends up horribly clashing with the established atmosphere. It feels like it's from another level, and frankly it feels like there should've been another (not pigstep (wtf happened to that)). Two intentionally infuriating levels, one sarcastically relaxing, one sarcastically sarcastic. At least the robot's sync is good
