Sorry for the late replay! The Linux version is online now. Since I don't have Linux, I would appreciate it if you (or anyone) could tell me if everything is working properly.

Actually both versions don't seem to be working right now. The Linux one seems to be corrupted or maybe it has a permission issue. Whereas the Windows one is just the Linux one: there are no EXEs! Perhaps for Linux it's better to make a .tar.gz or .tar.xz file. See 7zip: https://www.7-zip.org/download.html
Thank YOU! I'd rather be credited with my real name. No worries for the Linux version, it was a pleasure. FYI it wasn't your fault, it's an issue of AGS: https://github.com/adventuregamestudio/ags/issues/693
