Investigate your way in a branching noir horror detective game inspired by Lovecraftian horror and ancient Minoan myth. Analyze evidence, connect clues, and uncover dark secrets through genre-bending deduction mechanics. Face a sinister plot—and an ultimate choice.

Set in the smoke-filled alleys of a city drowning in secrets, Obsidian Moon is a text-based detective adventure rooted in 1930s noir and psychological tension. Players take on the role of Sam Carter, a once-respected homicide detective haunted by grief and failure, tasked with solving a series of interconnected murders through logic, instinct, and the steady collapse of his own sanity. Armed with vintage forensics, gritty intuition, and limited time, you’ll follow leads, interrogate suspects, and make costly choices that may bring you closer to the truth, or break you entirely.<h2 class="bb_tag" >Key Gameplay Features</h2><ul class="bb_ul"><li>10 Intricate murder cases that interconnect into a larger plot involving a sinister cult that aims to resurrect an ancient dark entity, plus Optional side cases that reveal the key backstories.</li><li>A haunting mystery - Psychological and chthonic horror inspired by the works of H.P.
