GoodSmile is a very talented Geometry Dash player, possibly among the top 20 best players in the game. He has beaten a wide variety of insane and extreme demons, and hopes to complete all the top 10 hardest demons in the game.  Goodsmile (aka, GS) is the one who verified the buffed update version of A Bizarre Phantasm by TeamN2. His hardest demon, as of now, is A Bizarre Phantasm or Betrayal Of Fate. GoodSmile has verified a sequel to Audio Excursion, Audio Extraction on 8/9/16.
Due to his bad computer, he has to record with a camera.
A 45-second video on his channel of angry birds has amassed over 250k views.
It took him 27436 attemps to verify the update version of A Bizarre Phantasm.
He didn't record A Bizarre Phantasm because at the time he played it, his relative was sitting nearby. It would be weird if he suddenly took the camera and started to record the screen. Later he rebeat it with a video.
GoodSmile is an incredibly inactive player most likely due to having a job at Pizza Hut and probably focusing on other things such as college/university or other potentially time consuming things.
