This is a game created in a similar style to flash games like "World's Hardest Game" and "Geometry Dash" with a level based progression system, designed to test just how well you can control the titular red ball, Baller.
And once you finish, really show off your skills in the Speedrun mode!
The controls of this game are either using WASD or the arrow keys to move, with space to decelerate and ESC to pause the game. The UI can be completely controlled by the keyboard, but the cursor works to navigate it as well.
