Unitale is an undertale fangame which allows you to make your own undertale battles! Think of it as a combination of undertale and super mario maker except in unitale you make battles by editing scripts which can be tricky at first but the more you play, the more easier it'll be! To create battles in unitale you must go to the file where the unitale application is located, open the 'mods' folder and if you just downloaded unitale you'll have to mods, 'Encounter skeleton' and 'Examples'.
