Serponge is a French Geometry Dash level creator. He became extremely popular in 2.0 for the fact that his levels are filled with elaborate, unique design and complex effects, leading some to call him "FunnyGame's successor". He is also known for creating the AlterGame series, which is a series of levels with different game concepts in. For instance, in Altergame VIII, you drive a car and dodge obstacles.
One of his AlterGame levels (AlterGame IV) was the 1st place winner in G4lvatron's contest. However, he did not mention that it was for the CC, not even in the level description.
Many people thought that Serponge will quit GD because he said he doesn't play that much GD anymore in his level "StufF". Despite that, he does not seem to be quitting anytime soon.
His level "Altitudinem gamva" was an unfinished collab with G4lvatron. It can't be continued anymore due to the fact that it was featured and star-rated by RobTop and only RobTop can delete starred levels. However, since the level was made free to copy, G4lvatron managed to finish it and Serponge updated it. However. the "gamva" cannot be removed from the title anymore.
He is currently created a game called "Succy Succ".
