Do you need a 7z version to be able to extract on linux? The people who do use linux and play this never told me this was an issue.
Before we were just embedding all the pictures to the html. But as we convert the interactive version into a different engine, we're going to have to keep the pictures separate till this happens. Hopefully this will happen in the next month or so. Azulookami's games are all html with embedded pictures, so you don't have to unzip anything to play his games.
Googled how to run zip files on linux. It seems some already come with a program that can already do this, while others you have to dl a program to extract the files. Doesn't seem like converting it to a .rar or .7z would work either without you having to get a program that can extract files.
Though this site says something different on unzipping files in chromebook.
