This is the Mobile Version of the Game that I made a while ago to celebrate the 3rd Anniversary of Undertale (Because you asked for it), so I recommend that if you haven't played Undertale or you played it, but you haven't reached this specific battle go and finish Undertale first and then come back and play this game so you don't get spoiled in the process ;3

The Game is your average 3dish battle against Sans. You know, that dude, the one that'll give you a BAD TIME.
