Mythos: Book One [v1.0.0.0] [Nine of Swords]

March 29, 2025F95

Overview:
A Supernatural Murder Mystery Comedy!
Mythos is an adult visual novel game set in a fictitious version of our world. You follow the story of the main character – which you may choose to be male or female – as they learn of the mysterious death of their ex-girlfriend. Soon, the main character finds themself fumbling through the hidden society of supernatural beings that lurk in plain sight. Some of them are very much like the legends suggest, while others couldn’t be further from what one would expect.
Will our hero piece together the puzzle behind the murder of Lisa Harrison, or will they be consumed by new attention they’ve brought upon themselves?
Mythos will feature multiple choices to solve the mystery, and relationship paths that can be monogamous, harem-based, or even celibate (if that’s the kind of kinky thing you’re in to).

Mythos, Book One is now a full story. Solve the mystery of Lisa Harrison’s death! Discover the supernatural world and secret societies that have lurked just below the surface. Eat some really questionable diner food. Pet a cat.

Seriously, pet the cat. What’s wrong with you?

I proudly present my complete game – hopefully the first of many!

2023-12-24: Chapter 5.0.1 Hotfix

There’s a bug in chapter 5.0.0 where if you make a particular choice (kissing Lisa) your character name will be reset to default (Kylie or Kyle depending on your gender).

If you use the default name, anyway, this won’t affect you. If keeping your custom name is important, use this hotfixed version.

All this does is add the new side images, which should be bug-free, now (but you know how that goes). The side images are all it adds, no new content. Only download this if you care about the changing expressions next to the text box.

Developer Notes:

This is the full release of Mythos: Book One, Chapter Three!

Note that saves made prior to the Chapter Three release require starting a new game – an unfortunate side-effect of me fixing code from when I was still learning how to do things.
