What a fun story! Good combination of light-hearted, sexy, and spooky. Very eager to see what Arthur's visions/past are about, and who this mysterious horse is. All of the artwork is very good too!
The in-game About page is missing the credits mentioned at the very end... and there were a handful of minor typos throughout. Do you plan to start a bug/typo list that people can contribute to?
Excited to see future builds!
