How-D is an American YouTuber born in Texas who primarily makes content around the popular rhythm platformer “Geometry Dash”. How-D created his YouTube channel back on July 15, 2015 and uploaded his first video titled “By Candle Flame | Preview | Geometry Dash” 5 years later on December 17, 2020. During his videos, mainly ones where he redoes main levels with a spinning wheel deciding which gamemode to use, he uses his own covers of songs, leading to his first song, “RNG”, a cover of Eden’s “XO” used in a Geometry Dash level by the same name. He is currently still making videos on the game today.
