Super Monkey Ball Jr. is a spinoff of the platforming game series Super Monkey Ball to the Game Boy Advance. It features 3D graphics mixed with 2D sprites in a third-person view, an uncommon sight to be found in a Game Boy Advance game. As with the other games in the Super Monkey Ball series, the objective is to guide one of four selectable monkeys inside their own capsule spheres to the exit by tilting the entire level.
Alyosha in this run decides to play the "Beginner" set of stages and completes them all as fast as possible.
You can see this run being played back on a real console here.
