CJ5Boss Gealgebra (Gealgebra in-game)is a relatively unnoticed developing creator. He currently has around 2000 stars and has created a few levels, none of which have been starred so far. His most enjoyed level so far is Tarantula, released in February 2017, using new 2.1 blocks. He currently star grinds and also works on many mega-collaborations.
In a recent YouTube video, Gealgebra said that he will be working on an Element series soon.
That video was, unfortunately, taken down three weeks after its upload.
