Lost Lagoon is a fantasy dating sim adventure made by Palmeira Studios with RPGM. You play a man who lies unconscious on a small boat after a heavy storm at sea, while a mysterious voice calls to him in his dreams. The island’s fate rests on you, so the story follows your search for your true identity and origins. It uses 2D animated CG artwork.
The current build is v0.5.0, released May 12, 2026 for Windows and Mac in English, with no censorship. Development is ongoing. This update removed all AI-generated assets and replaced static renders with fully animated scenes plus custom sound design. It also revised the dialogue and presentation of each girl to give her a more distinct personality. New gameplay systems include a Lust Gauge, gifting and compliments to improve relationships, and activity spots with a job-board.
Developer's description
There is a heavy storm at sea. You lie unconscious on your small boat. A mysterious voice calls to you from your dreams to stay alive. The fate of an island depends on you! Can you find out who you really are and where you come from?
v0.5.0
What you can expect from this update:
As promised,
the AI era is officially over.
Every single AI asset has been removed.
Animated Scenes:
No more static renders. Experience the island with fully animated scenes and custom sound design for a truly immersive experience.
Unique Identities:
I’ve overhauled the dialogues and styles of every girl. I'm still working on my writing and character development skills, but I tried to give each girl her own individual style and personality for this update.
New Mechanics & Gameplay:
The Lust Gauge:
A new way to track your progress and tension with the bachelorettes.
Gifting & Compliments:
You can now actively woo the girls with items they love or a well-timed compliment to improve your relationship!
Activity Spots & Job-Board:
Keep an eye out for interactable spots on the map that trigger extra character scenes and flavor text.
Combat Overhaul:
A batch of new weapons, armor, and gear has been added to the database to make combat more engaging.
...and much more!
Content & World Building
Chapter 1 & 2 are Complete:
