2/Dec/2025 - Updated to v0.8.1

Hey guys,
This month, I’ve finally started adding the story characters and some introduction scenes, as
well as a big new scene for Madeline and Rebecca.
The story scenes will normally show up much sooner in a new playthrough, but I’ve added some
hints so you can still trigger them in your current saves.
Next month, I’ll focus on adding more story content and a new scene for Kate.
I hope you’ll enjoy it, and if you have any questions or comments, please let me know!
All the best,
Faerin

Overview

It is good, no blue balls.

Gameplay

Plays like a game, has grind.

Downloads

Midnight Sin v1.01 Steam + Patch (not needed)

Screenshots

Android Port Info

1 Save Location

It always is in Documents/INCG_Saves/incg.[gamename]

This folder has a /game folder that works like a PC game folder, you can add ugu.rpy (Universal Gallery Unlocker) and 0x52 Universal Mod, rpa files, patches etc.

If you can't find it in INCG_Saves, I did a cock up and it will be in Documents/Renpy_Saves folder.

Note: This does not apply to official apks, they usually don't have external save location, some do (e.g The Inn). If something asks for external file permission when u first launch it, it should support external save, most of them live in Documents folder.

2 Dialogue Box has weird text ?

Check if it is a port that has INCG Menu, if it exists, there is high chance that switching between Multi-Sayer/Scrolling TB will fix it.
Otherwise you can report it and I'll try fixing it or give up :P.

3 Android Install, Google Play Protect and Other app police like Xiaomi Security/ Anti Virus etcs

Google play protect sometimes triggers, turn it off or just ignore it and install, it will work.
The reason is that my ports asks for storage permission for external Document folder save, to not trigger it, I have to remove that feature, which is not ok, so there is no way around it.

One other option is playing online, which I now offer in the Play section. This costs somewhat a bit, so I can only keep popular games there.
If Online version is available, there will be link to it in the post.

4 IncgWT, IncgCheats, IncgUnlocks !?

Walkthroughs I make are usually shitty, Cheats a bit more useful than my Walkthroughs. Gallery Unlock - most useful and predictable at the moment.
Doing incest patches is planned but unsure.
