Due to our installer's limitation we packaged this game as a .tar.gz archive, instead of the regular .sh installer.
Interesting. May I ask what that limitation is? It can't be size-related, since there are way bigger Linux .sh installers...
Size limit for a single file inside the archive, otherwise there is an error on extraction by MojoSetup. More than likely fixable, it's just that I don't have time for that right now, so sorry again!
