Like ... most every other VN, yes?
We’re happy to present the first official world demo. It covers about one tenth of the whole story, and it’s still missing some of its parts. But it’s playable, it’s (we hope) readable, and it even contains a nasty ending. (We’re certain it won’t take you long to discover it.)
Please download it here. (Includes Linux, Mac and Windows versions. If anyone needs an Android version, just let me know.)

If you enjoy Aurelion: The Coin and would like to help:
1. Join our team. We can never get enough artists: that’s why that scene lacks a CG ... you’ll see which one.

This project will (most likely) be driven by donations only. We make sure to split any money thrown our way among the whole team, proportionally to the efforts of each member.
2. Donate. Our PayPal account is linked to my email, kalin-dot-nenov-at-gmail-dot-com.
3. Spread the word.
... What have we missed?

We’re always open to new ideas and contributors.
Oh, and my name is Kalin M. Nenov but I’d rather you call me Kal. I act as the creative director and All-Around Prodder of this project. I’m always looking forward to questions.

P.S. “Prodder” is:
a) not a misspelled version of “Producer” or something, but a neologism coined from the verb “prod” (and it’s not a joyful duty, mind you);
b) an instance of my odd sense of humor. Please do not feel offended by anything I may tell you. I’m most likely kidding.

P.P.S. I've added a brief introduction to our creative team (tentatively known as "Aurelians") on my personal blog.
