FunnyGame (Also known as Caustic which is his alternate account) is a South Korean player and level creator in Geometry Dash, who has been playing the game since Update 1.2. He mainly creates revolutionary effect levels that contain unique design, and continually push each update to its furthest potential. He has also participated in a number of mega-collaborations, the most notable one being Yatagarasu.

Sometime around Christmas, it appeared that the talented creator had quit, changing both of his icon colors to black and deleted all of his posts. Recently he has updated his icons and public messages, returning to the game, and he also streams occasionally and uploads levels every few months.

He is often regarded by most people as the absolute best creator in Geometry Dash, along with Serponge.


In early 2017 FunnyGame released a level called "Variety" which was his 1st 2.1 level. Viprin did some research and eventually discovered that the level was built by somebody called GeoGame who had access to FunnyGame's account. Later, FunnyGame revealed that he had quit and he transferred ownership of his account to GeoGame.

  • His nickname is BunnyGame.
    • All of his 2.0 levels the in-game text changes from "FunnyGame" to "BunnyGame" when the player dies or collecting a user coin with the name visible on screen
      • For example, in Abyss, you get a "BunnyGame" message when you die at the part where there is a text saying "Made by FunnyGame". In Unity, when you die at the part where there is a text that said "FunnyGame and TriAxis", the text changes into "BunnyGame and FriAxis". In -Sirius-, the "BunnyGame" will appear when you collect the first coin, and in the end, if you wait a bit after completing the level, the background will turn black and a message will appear saying "Bunnygame". In The Honorable Final, if you die that the part where there's a text that said "FunnyGame and Serponge", it will change into "BunnyGame and Derponge". It'll happen at the end of the level too if you collect the 3rd coin. In Deadly Impact, right before the drop, there are a few messages appearing on the screen, one of them which is "bunnygame". In Lonely Travel, after completing the level, you need to wait and there's gonna be a "BUNNYGAME" slowly moving to the left of your screen, On the blue screen bossfight at "Puzzle Trials" you could see the text Bunnygame on the error message, but it is very difficult to spot.
