Yay for a boss fight
Yup, I found some of the koopalings highly annoying though towards the end since they took a bit longer to defeat for one reason or another and usually ended up trying to shrink then kill Mario or Luigi. Good times though.
The drums are nice and speedy here so that sounds good to me anyways so great work there. The trumpets sound really nice too and provide a dark battle piece. The bass line is simple and sounds twisted yet awesome.
Overall, good cover.
