A quiet, cryptic space explorer where you puzzle out planetary mysteries across procedurally generated galaxies. Strange, slow, and genuinely unlike anything else.

MirrorMoon EP is a first-person space exploration game built almost entirely out of atmosphere and inference. You start on a red planet beneath a peculiar moon, and from that single strange location the game asks you to figure out, through observation and experimentation, how things work. There is no tutorial. There is barely any text. What there is: a beautiful, minimal visual language and a soundtrack that hums with the particular loneliness of deep space. Santa Ragione made something that feels less like a product and more like a found object. The core loop is navigation-based puzzle solving tied to planetary exploration. Each star system is procedurally generated, and the galaxy itself is shared across players in a loose, asynchronous way, meaning someone else may have already named the star you just landed near. That detail is either charming or meaningless depending on your tolerance for ambient multiplayer ideas that exist mostly in concept. The single-player experience works entirely on its own terms regardless: you rotate and manipulate the moon to affect what happens on the planet below, unlocking paths, revealing geometry, slowly untangling each location's small logic. It is deliberate and quiet and occasionally baffling in ways that feel intentional rather than sloppy. Who is this for, honestly? It is for people who consider Kentucky Route Zero a reasonable Friday night. It is for the player who will sit with an unexplained mechanic for twenty minutes because the act of sitting with it feels like part of the point. It is not for anyone expecting momentum, clear objectives, or a sense of progress that rewards them on a predictable schedule. The mixed Steam reviews reflect that split cleanly: a significant portion of players bounced off the opacity and the pacing, and that reaction is not wrong, just incompatible with what MirrorMoon EP actually is. What works is the mood, which is so consistent and so carefully constructed that you feel the designers made every decision together, even when a system is frustrating. The visual palette - deep reds, sharp geometry, stark contrast - holds together across every procedural location in a way that procedural games rarely manage. The music deserves specific attention: it is textural and sparse and does that thing where you stop noticing it consciously and it just becomes the emotional weather of your session. For a game this compact, that kind of soundscape discipline is rare and worth acknowledging. What doesn't work as well is the moment when the procedural scale starts to dilute the sense of discovery. Early hours feel weighted with meaning. Later, once you understand the systems, the galaxy can start to feel like repetition with a fresh coat of generated paint. The game seems aware of this - it is short enough that it doesn't overstay - but there is a slight hollowness when the mystery wears thin and the underlying puzzle structure is smaller than the cosmic presentation suggested. At its best, MirrorMoon EP is a genuinely transportive piece of interactive design. At its plateaus, it is a pretty screensaver you are slightly lost inside. Kai, Scout Team

GamerScout Verdict

Worth it for mood-first explorers who can tolerate opacity; everyone else will bounce off the silence inside an hour.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
