Created on the basis of Undertale and supporting the Lua-mode core. This means that it provides data and basic sprites/sounds used in Undertale's battle system, allowing you to make your own battle, either using the data that's already present in the app, or you can also import your own sprites/sounds and program the fights however you want. (There have been speculations regarding the possibility of adding bits of the map into Unitale, but since it's only speculation, confirmation is needed. Until then, when you try to Flee a fight, the message displayed will remain the same, "...but you realized the overworld was missing.")
