The game features 20 levels each with its own objective. Depending on the objective each level will require different skills from the player. Some levels are action based while other are more puzzle like. For example more strategic levels involve linking an exact amount of bubbles, while an action level might be more about removing bubbles as quickly as possible. After completing a level's objective the player can choose to move on to the next or continue playing.
The game has a vector graphics style and features music from the Belgian band Silence. The game also features a colourblind option which turns the otherwise colourful background into grey.
