ok, you ripped ut fonts and sprites, songs but edited so it uses same soundfont from undertale (example; white house song just being ruins theme but just beats changed) , sfx, concepts, and literally the art style and gameplay aspect. this is a fangame by definition, and it ILLEGAL to make this paid. using others work and profiting off of it is ILLEGAL.

another thing is that this literally uses tml engine, a engine FOR UNDERTALE FANGAMES. weather its changed enough or not you still gotta credit that person anyway, and its still undertale.. there is so much fraud and stealing behind this game that its so awful. do better, and stop making this a paid game. its ILLEGAL.
