One bleak island, four dead strangers, and about an hour of slow-burn dread that earns its atmosphere without a single jump scare.

I went into The Moon Sliver expecting another lo-fi walking sim that coasts on vibes and delivers nothing. What I got instead was a tightly constructed hour of environmental storytelling that lingers after the credits roll, which is a better return on investment than most games ten times longer. The setup is deliberately sparse. You are the last person on a small, wind-scoured island. Four people lived here: Able, Isa, Daniel, and Ellie. None of them are around anymore. The core mechanic is simple but cleverly executed: walk through spaces and text fragments appear on screen, each one a splinter of memory or observation. The non-linear structure means the order you collect these pieces is partly your own doing, and the game uses that to keep you genuinely unsure which of the four characters you actually are for most of the runtime. That identity ambiguity is the smartest thing the writing does. The story concerns betrayal, faith collapsing under pressure, and a supernatural force called the Woodland Teeth that the island's residents believed a relic, the titular Moon Sliver, was keeping at bay. The one piece of gameplay with any mechanical teeth is the flashlight system. Your torch runs on a charge, and underground sections force you to toggle it strategically, dashing between recharge points in a dark maze while narrative text keeps scrolling. It is not a complex mechanic, but the tension it generates in those tunnels is real. The day cycle also functions as a soft structure: night only falls once you have found enough story fragments, which gates access to the mountain and the final sequence. Some players have reported that missing a key interaction early can cause confusing dead-ends, so the community wisdom of exploring thoroughly before entering buildings is worth heeding. There is no save system, by design, but the runtime of roughly forty to sixty minutes makes that a non-issue for most. The weaknesses are honest ones. The graphics are blunt, even by 2014 indie standards, and the lighting does more atmospheric lifting than the geometry deserves. Overlapping text boxes are a recurring complaint, and the point-and-click interaction has a fiddly radius that can frustrate. Replay value is essentially zero once you know the story. For players who came to David Szymanski through Dusk or Iron Lung looking for something action-adjacent, this will feel like a different species of game entirely. It is best understood as a short horror novelette with a flashlight battery as your only resource to manage. If you are the kind of player who finds Dear Esther too passive but considers Amnesia too much of a game, The Moon Sliver occupies an interesting middle ground. The atmosphere does real work, the story structure is smarter than it first appears, and the final sequence in the mountain lands with quiet, unsettling force. Go in knowing what it is and you will probably find it worth every minute of that one uninterrupted sitting. Alex, Scout Team

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.
