I've made multiple failed attempts at virt arrangements. It's the harmonies that get me.
I like when people post their thoughts in the Mega Man competitions, so here are mine:
Cosmic Sounds: Love the minimalist intro and the way it sets the mood. It took me repeated listens to locate the source usage throughout the track, though (and I'm pretty familiar with Shovel Knight). I can hear that it's there, but it's subtle to the point that it comes across as more of an original track.
Gario: This one starts leaning the other way (toward straight cover territory), but there are definitely Gario touches sprinkled in. Despite falling short of what I know you're capable of with more time on your hands, it's still a very enjoyable track.
Supercoolmike: Harmonic soundscape is a little sparse--the original track has fuller chords in its favor. I could see it as being representative of more of a bleak scene rather than an epic final battle, though it does leave me wanting a little more depth.
Ultimately, my decision between Cosmic and Super came down to source usage. Separated from the context of ReMixing, I might've picked Cosmic over Super, but I feel source recognizability is too important of a factor for this kind of competition. I understand opposite votes, though.
Overall, I'm glad to see four different games get represented! I hope this trend continues!
