Exciting news, everyone! I just found out this morning that I've been whitelisted for Geometry Dash, meaning you can use my music on Newgrounds to construct a level. The funny thing is, I never asked to be whitelisted, which probably means a GD moderator just added me at some point. I consider this an enormous honor, and if that moderator happens to be reading this, THANK YOU!
You're free to use any of my tracks in the game. I would appreciate it if you could let me know when/if you use a track of mine for the game, but you don't have to. I'm just curious what track you're using, how the level plays, etc. Who knows - maybe this will even motivate me to play GD for the first time, haha.
Either way, massive shout-out to RobTop Games and the entire GD community. Me getting whitelisted easily made my day. ^_^
