"You're gonna have to try a little harder than THAT!" -- Undyne the Undying, 201X

So, I know there's a couple arrangements of this song on Notessimo already, but in my opinion, they aren't all that great compared to the original.

Seeing these, and trying to beat Undyne the Undying myself, inspired me to do a version which, I'd say, is the most accurate so far! But that's just me; what will you guys think?

Enjoy, and stay "determined"!
