Geometry Dash B is a Medium Demon 2.1 created by Motleyorc and ScorchVx. It is designed to resemble a beehive and features a boss fight with a large bee.
Motleyorc sent ScorchVx a Discord message explaining that he wanted to create a bee-themed boss fight in February 2017. ScorchVx asked if he could help, and Motleyorc agreed. After reaching a decision, they named the level "B" and started developing the gameplay. On May 21, 2017, Motleyorc published a video of the finished level. The level took just over three months to build.
Geometry Dash B contains a total of two user coins.
The first coin is at 19%. To get it, the player needs to take the lower path and fly between the two bees without touching them.
The second coin is at 45%. The player needs to ignore the green orb and fall down to the platform where the coin is.
