Hey, the Windows download is named "PC".
What is that supposed to mean?
That if a PC runs on Mac OS or Linux then it is not a PC?
That all PC have to run on Windows?
Please play fair, acknowledge that Mac OS and Linux are as much PC's OS than Windows and righteously call your downloads Windows, Mac OS and Linux.
Also, there is an issue with your visual novel, I just bought it from Itch app and I cannot download it, the button keeps saying "Buy now" when it should be saying "Download now" as if Itch app doesn't acknowledge that I own this visual novel.
Then I tried to download it from Itch website without using Itch app and the website does acknowledge that I own Lily's Day Off and I did was able to download the Lily's Day Off Linux v1.4.zip file on my PC.
However I unziped the file but the visual novel will not launch...
Did you test your visual novel on Linux already? Does it work?
