So, for transfer it on Windows, I just make a copy from Linux? How work the DRM?
Amanita Design games are always DRM free and there will be no need to copy from Linux to Windows.
When you purchase Botanicula an email is sent to you with download links to the three separate versions available (Win/Mac/Linux). Download all those files, save the Win and Mac installer files away some place for later use, and meantime load and play the Linux version on your current computer.
When you want to move to a Windows machine load and launch the Win installer you downloaded when you bought the game.
Ah... But the question of copying your Saved Games is another matter for another thread. Come back and let us know when that time comes and we'll do what we can to help you then. ;~)
