I added new 21 Achievements to unlock, two working settings, delete file option and unlockable difficulties. In the future i will probably add more Achievement, but for now 21 is enough. Also, there is two secret ones too, good luck getting them ;)

(Also, if you are wondering: no, your old save file won't lose anything. You will have all your old stats, and if you had, like 1 win, you will get Achievement for that instantly.)
