His editor is glitched as the music will not sync up properly with the level after pausing or using a start pos when in the editor. When actually playing the level, everything is fine.
His YouTube account was suspended without warning or reason on April 17, 2015. The account was recovered in June, but the previously uploaded videos were unavailable until a few months later.
On 22 June 2016, his Everyplay account glitched. Uploading videos directly from Geometry Dash to YouTube no longer worked. This has happened to many Geometry Dash players. This fixed itself no later than 3 July 2016.
