Overview

Idle Harem Dungeon is an idle RPG for players who want a low-effort corruption fantasy with a demonic twist. It plays slow and steady, favoring repetition and gradual power gain over tension.

Story

A demon lord, killed long ago by a heroine, is cursed by the Goddess to relive that death endlessly. Each cycle carries forward what was learned before, giving the demon a chance to grow strong enough to finally defeat the Goddess' chosen warriors and turn against her.

Gameplay

Combat runs on its own as waves of adventurers arrive to strike down the demon lord, while the player spends the time between fights building up strength for the next cycle. Defeated warriors can be seduced and corrupted, joining the demon's side as companions who assist in later battles. Progress carries between cycles, so each death brings the character closer to breaking the loop for good.

Features

Idle combat loop built around repeated cycles of death and growth
Corruption system that turns defeated enemies into permanent allies
2D animated scenes tied to specific companions
Monster girl and male-domination themes throughout

Installation

1. Extract and run.

v0.2

OLD SAVES SHOULD NOT WORK ON THIS VERSION (You can try, but it'll probably crash)
Added a new girl, Tory.
Added 3 different scenes for Tory.
Reworked the game's systems so that enemies no longer scale in strength on their own
Reworked the "Full Employee Benefits" skill to allow the player to increase the strength of enemies (stronger enemies give more experience)
Bosses (the girls) now no longer spawn on their own. Press the "Spawn Boss" Button to summon them.
Bosses (the girls) will join and fight on your side after you defeat them 3 times
Reworked the "Speedrunner" skill. Now, instead of halving the amount of enemies required, it halves the bosses' stats.
Added Post-Processing to make the game look better (this time it should have next to no performance impact)
Improved the way the game handles textures and reduced RAM consumption (it wasn't really a problem before, but improvements are nice)
Made the main menu look nicer
Fixed bug where reducing too much the spawn timer of enemies made them not spawn at all
Fixed other bugs that I don't remember
Added a "Coming Soon" banner for the game's Steam page
