Lost Lagoon is a fantasy dating sim from Palmeira Studios, built in RPG Maker with 2D gameplay and 3D CG animated scenes. You play a storm survivor on a remote tropical island, helping the small companion Gabriella rescue the Goddess from Demon Queen Nyx. The game combines exploration, adventure, and relationship scenes, while the island’s residents offer aid in their own intimate ways. Themes include fantasy, dating sim, and harem.
The current build is v0.5.4.1, released September 9, 2026 for Windows and Mac in English, uncensored. Development remains ongoing. This update adds Kaela and Goblina main-story love events, a Mara midday love event, an Elara repeatable morning scene, eleven dream sequences for each main girl, a refined Fiona and Lyrana love event, a revised Slimegirl scene, and two short cutscenes after Nyx encounters. New story content opens the Desert, adds a Fire Temple puzzle, frees Sheila and Lamiia from a Sand Giant's hold, and introduces new weapons and armor for tougher monsters.
