Well I didn't manage to get LBA 2 working, I put all the files into the twine directory. The only way I could get the installer to see the GOG file was to rename it so it extracted the movies, but I couldn't get the game to run at all
There is no "save" feature implemented currently, its on the ToDo List, but I don't know wether this project is still alive. Thats why I prefer using dosbox to run it. There is an autosave feature though, but I don't know how often it saves.
