This is like MajesticPie's "Undertale Boss Fight" game, but Papyrus-themed with more attacks that are more difficult to dodge, thus why you have more HP. 2.0 You can use W,S,D and A for the Soul to move. 3.0 New music in the battle called "Synthesia- Undertale - Bonetrousle101,000+ NotesBlack MIDI" and more battle with Godzilla's purple fire ball.
