What if the battles in Dancetale were just OSU-Games?
Like Papyrus battle is the Drum osu (Osu Taiko) Because there are a lot of drums in his theme.
And Sans battle is regular Osu, but insanely hard, and your cursor suddenly appears somewhere else on the screen because of his “cheating” from time to time.
And Toriel has this really easy mode regular Osu, but it’s still hard becasue you are crying and can’t see the goddamn screen.
And Alphys has some nightcore version of her theme. (She also battles you, just because she loves osu)
And Undynes battle is OSU Mania (The one that looks like Piano keys at the bottom and a long road upwards)
And Mettaton is a couple of battles, all classic Osu, but you have to pose while playing it. Also the music is mostly Nightcore version of Vocaloid-Rock songs. That he made himself. With his own voice as voicebank samples. Because he needs to be that extra.
And Asgores is also Standart Osu, but he is not dancing himself, not really taking part himself because he doesn’t want to fight you but feels like he must.
And the Flowey fight is Osu Catch, but really hard and glitchy.
And the Asriel Fight is regular Osu at first, but with a very flashy background, the Osu Taiko with even flashier effects then ussually, and at last Osu mania when you get to the second stage, because it looks a bit like guitar hero, and it fits to the music.
