Overview

Seahaven's Fall is a 3DCG adult sandbox for players who want a corruption-focused story with transformation elements. The tone leans dark and magical rather than lighthearted.

Story

A normal student's life changes after a run-in with a powerful succubus, who curses him and drags him into a world of magic and corruption. He has to decide whether to resist her and stop her plans for the town, or give in and help her spread that corruption himself, all while still trying to manage his schoolwork.

Gameplay

Play unfolds as a sandbox built around a school setting, where daily routines, energy-limited choices, and NPC interactions shape how the curse and the corruption spread. Dialogue options tied to energy costs and status effects tie into how the protagonist's transformation and relationships with monster girls and other characters progress over time.

Features

Monster girl and futanari elements woven into a school-life sandbox
Gender bender and transformation mechanics tied to the curse
3DCG art style with an evolving town environment

Installation

1. Extract and run.

v0.2 Release
A very small update with no new content, just bug fixes and a couple important features:
Save Progress : Whenever you rest in the bed your progress will be saved. This first implementation just overwrites the last save, but I can add save slots later.
Web support for Mac : I've updated the engine and the latest version should be playable on Mac. I don't have a Mac to test this so if anyone has issues please let us know.
That's it. Next update I'll focus on adding new content instead, but these were things I wanted to get out of the way before going any further.
v0.19 Release
Added the first day of classes, with a bunch of new people to meet around the campus.
New map: university dorms, you can rest here at night, change clothes, hairstyles, etc.
New location: university library, where you can research even the most obscure topics. In the future you'll be able to learn more about magic, discover new spells here.
New location: the hotel, a bit to expensive for a poor student, but maybe they've got some work to do?
New job options: check the notice board in your dorm for more clues.
