Overview

Monsters Abyss: Operation is a turn-based adult RPG for players who want short, focused monster-battle encounters with a female protagonist. The tone is direct and mechanics-first, without much setup.

Gameplay

This demo introduces the core combat mechanics: turn-based battles against monster enemies, with a mix of animated 2D encounters. The player fights through a small set of foes to get a feel for how the systems fit together before any larger content is added.

Features

Turn-based combat against distinct monster types
Animated 2D art for battle encounters

Installation

1. Extract and run.

The next update will be "Monsters Abyss Trial Version 1.0", and the remaining bugs will be wiped out and new monsters will be added in the February 2022 article, Gatchiri Plan and above. After that, it will be updated to April, June, and August with the goal of once every two months. In the month when the trial version is not updated, some animation will be uploaded.
We have updated the above contents of the Gatchiri Plan accordingly, so please check again.
Thanks for the share gjjfff
