That's exactly what I tried to do a year ago, and it worked! But since there's no game options other than the controls in the DLC I can't really do anything. It also might be linked to the fact that everytime I would try to install the archive with the game files it would delete itself automatically after a few seconds. All I know is that I want to try it since the original was already really nice.
P.s. Even though there was no way to clear data in the game itself, is there another way outside the game?
