Sins and Desires is a free online detective visual novel where you play as detective Felicia, sent to the foggy village of West-Alben to investigate the disappearance of aristocrat William. Every scene unfolds through story-driven dialogue and branching choices that directly shape how the mystery plays out and which ending you reach.

The game features three distinct romance routes with characters Albert, Felix, and Victor, and a relationship system that tracks your decisions throughout the story. Choosing different dialogue options on repeat playthroughs reveals new clues, alternate scenes, and endings you missed the first time. The atmosphere does a lot of heavy lifting here – a crumbling dark mansion, a lake shrouded in fog, and a village where every resident seems to be hiding something. If you want the true ending, pay attention to the smaller choices early on, since the relationship meters shift more than you might expect.

Fans of interactive story games, romance visual novels, and detective mystery games will find plenty to dig into across multiple runs. This is a solid pick if you enjoy games like free HTML5 visual novels, casual story games with choices, or browser-based detective adventures with romance elements. Play Sins and Desires free in your browser with no download or sign-up required – perfect for quick sessions or longer story sessions on any device.
