And they seem to have a pretty thorough FAQ for linux users, and in particular linux steam users.Our future games will be developed with Haxe/OpenFL so that we can get true native support for Linux without having to mess with this junk.
Also they have a linux demo to see if it works and encourage to contact them if any difficulty arises:
Btw, just got the bundle with an extra weight on Ren'Py, Stronghold and Magic Diary.We HIGHLY recommend that before purchasing the game, make sure the linux demo works on your system. If it doesn't, send an email to [email protected] and tell us what's happening. We want to support as many linux distros as possible even though Adobe has made this difficult for us.
