Review notes
Matter is worth a closer look if you want strong atmosphere, emotional story, controller friendly, and short game.
Best for players who want strong atmosphere, emotional story, liminal, and controller friendly.
Check more carefully if you dislike unclear onboarding and technical roughness.

PacingIt is better understood as a compact experience than a long hobby game.
narrative-adventure
Play styleThe experience is more story-and-place driven than systems-heavy.
replayable
FitThe structure gives reasons to return rather than finish once.
confusing-onboarding

buggy

Steam review snapshots
At some points I felt like something out of a Marvel movie, making insane leaps and crashing to the ground on one…You can basically moon jump, and even on fast moving platforms, you seem to have some insulation from their inertia.There is a definite epochal progression in atmosphere through three pairs of chapters and a denouement, which is reflected in the pacing…Matter is kind of like a platforming walking simulator with weird physics…so basically, you jump around a surreal landscape with strange gravity…Why it fits
Check it if you want action filtered by single-player.
