That can happen, as Ren'Py has been very prone to give false positives for ages now (you can search these terms on F95 yourself). That said, this is still the first time I have heard about false positives on Linux! What distro/AV are you using?I get a virus warning for the Linux version.
Naturally, that applies only if you downloaded the game either directly from me (links on my Twitter/Patreon/Substar) or from here. I can't vouch for the game if you got it elsewhere!
