No worries ! I bought the game on steam and was able to copy the game files to another folder, so DRM-free version for me ! Yay ! Only thing is I can't show my appreciation by choosing the price...maybe you could set-up some "add-ons" on steam, that you would sell 1$ so that people can give you a little more ? Not sure that's worth the effort for you though :)
Cheers and great games by the way !
