The Moon Sliver

A Adventure game by David Szymanski, released in 2014

No Rating🔴Niche / Inactive🏆Proton PlatinumPC (Microsoft Windows)

The Moon Sliver is a short narrative-focused non-linear exploration game, with elements of horror. It features a unique narrative mechanic that blurs the line between story and exploration, where interacting with objects and even simply moving around will reveal fragments of narration. As you piece these fragments together, a story of guilt, loneliness, and faith begins to take shape. And it becomes increasingly obvious that something is hunting you...
