making your way through spaces of angular, alien structures. levels alternate between cramped, even claustrophobic moments and wide open areas with an epic sense of scale. not exactly a "walking sim" because the "making your way through" involves a consistent rhythm of puzzle platforming that's not highly difficult, but nontrivial enough that i could see people getting stuck or frustrated at points. moreover i wouldn't say the platforming and movement "feel good" in a way that you'd typically hope a platformer to feel, so even if almost all the sections in the end only took a handful of tries at worst, it often felt a bit painstaking, which might well be the intention. the way this game's level design unfolds, and the way the levels play with your perception of light as you try to progress, and especially the way the levels play with your perception in more extreme ways as the finale gives way to intense psychedelia, is unlike anything else i've experienced in a game. the ambient electronic music is what really seals the immersion though. i don't think its an overstatement that even with the beauty of the game's architecture, it'd be in a lot greater danger of becoming a slog without the music. so many points here where as soon as it really kicked in i felt so much more keyed into the play process.
