alright so i see the comments asking for my newer songs to have access for geometry dash, thing is they are enabled for it, just i think they're bugged in the geometry dash system atm.
so far anything from my song 'Sinister' to recent uploads like my Ronin album and my Compilation seems to not be available for use in geometry dash albeit the toggle is on. i emailed Tom Fulp about it sometime earlier this month, he sent over a request to get it fixed so i think it's getting sorted out but i can't say for certain since it ain't my limelight of things i can figure out.
so until then anything new so far won't be on geometry dash until this bug gets fixed. im sorry.
