We are not being Linux users ourselves, so it is difficult to test it properly. I'm afraid we don't know much about how the Linux engine works, which is why we don't offer a Linux version on our store (we don't feel right selling a product we can't support properly). As for why this specific game doesn't work, it is probably because we made some changes to make the iOS port and it seems to conflict when compiling the Linux version. We are unsure what those are, but I believe the AGS Linux Engine wizards are doing something about it.
