Undertale (or UNDERTALE, Undertale or Undertale) is a computer RPG developed by indie game creator Toby Fox.This work is a catch phrase of "an easy RPG where no one dies", and the major feature of the system is that it is not always necessary to defeat monsters in battle.It is a quiz app with all 30 questions in a 4-choice quiz format.The difficulty level is obvious, so it may not be so difficult.I hope you can feel free to install it to kill time.If you have any request, we are waiting for a review.
