An update on Shmexagon(new name, have a better one, comment below). If anybody is willing to send in music resources, I'd be glad :) (has to be fast paced and energetic :P)

The key is highlighted, You'll have to put BGMPLAY in front though, but you probably knew that. Also maybe Hexadodge?

also feel free to change the guitar instrument to suit the game better! Or just changing the song

Hexadodge sounds like a great name, it also doesn't sound like it inflicts with the other name Hexagon, :P

I also modified the tune to make all notes one semitone lower and got rid of some sharps because it felt kind of too high pitched for my tastes(in a bass :P)
