Lost Lagoon

Overview:
Stranded on Lost Lagoon! ️
Lost Lagoon is a mix of RPG, adventure, and dating sim — filled with exploration, charm, and a touch of mystery. Check out the Lost Lagoon Patreon for the latest updates, new content, and release news!
After a storm leaves you stranded on a remote tropical island, you and your tiny companion Gabriella must work together to free the island’s Goddess from the grasp of the Demon Queen Nyx. Luckily, the island isn’t as lonely as it seems - its lovely inhabitants are more than willing to lend a helping hand…in their own special ways...❤︎⁠

Spoiler: Change-Log

v0.5
The Big Shift: From AI to 3D
The AI era is officially over. Every single AI asset has been removed.

• Fully Animated Scenes: No more static renders. Experience the island with high-quality animated scenes and custom sound design for a truly immersive experience.
• Unique Identities: I’ve overhauled the dialogues and styles for every girl. I'm still honing my writing, but I’ve worked hard to give each bachelorette her own individual voice, style, and personality.

⚙ New Mechanics & Gameplay

• The Lust Gauge: A new way to track your progress and tension with the girls.
• Gifting & Compliments: Actively woo the girls with items they love or a well-timed compliment to build 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: I've added a batch of new weapons, armor, and gear to make combat more engaging and tactical.

️ Content & World Building

• Chapters 1 & 2 are Complete: This includes the first two Love Events for every main character.
• More Playtime: A standard playthrough (no speedrunning!) should now take roughly 5–6 hours.
• New Locations: Explore the Public Restroom, the Farm Barn, and get a sneak peek at the Monstergirl Resort (WIP), featuring the beginnings of our village-building mechanic.
• Patreon Exclusive: The expanded premium area is ready for my Tier-3 and Top-Tier supporters!

IMPORTANT: Save File Info
Because of the massive changes to the engine and assets, old save files from previous AI versions are NOT compatible. You will need to start a fresh journey to experience the new Lost Lagoon correctly.

The Good News: You can find an Early Access build on my PATREON that will provide premade save files for future updates.

This is an AI free remake by the same Dev, game is different enough I thought it warranted a new thread of it's own, I will possibly need to add the discontinued tag to the AI version but we will wait and see for now.

Looks great, cant wait to see more. Not that I'm against it, but some koikatsu games go a bit heavy on the pancake nipples. Stupid question, are people into this? The level here is strangely tolerable. I'm not sure if it will awaken something in me.
