DLsite: https://www.dlsite.com/maniax/work/=/product_id/RJ361715.html VirusTotal: none because there's no .exe file Latest version, Ver.2.0.8, taken from anime-sharing. As you've noticed, there's no .exe file, meaning you copy the "www" folder into the main game's folder and basically just copy what the screenshots tell you to do. Slow seeding at first.
