Muffet... a spider... hoo boy was it suprising to say...
That I actually do love this boss.
Yeah I like muffet, I like her design, I like her gimmick, I don't find her annoying. Annd her theme, while originally glosed over by me, it's one of those that if you listen to it multiple times, you like it more and more. It fits the frantic rush you have to go through with this boss, while making it clear you're stuck as well.
Needless to say, the way I immagine Undyne's... trapping spell, is more of a series of purple webs that the heart becomes... linked to. It has enough stretch from the body to the web to stick around 3 lines of web constantly. But when Cupcake chases you, I immagine the heart just jumps more and more up into the purple web, and when he's gone or falls off, the heart simply ricoches back because the web can only extend so much.
Not a big fan of spiders, but yeah! Granted, I'd think if I were in this situation as portrayed, I'd be freaked the hell out...

WARNING! During this art challenge I will spoil MANY THINGS during the game. Both in art and text! If you want to play Undertale I recommend you do it FIRST and then look at these pictures. Thank you!
