This game is a different spin on the de Blob series. In this game, de Blob goes inside the buildings of Chroma City to rescue the citizens one by one. The goal of the game is for de Blob to find the best way through mazes to rescue as many graydians as he can without crossing his own path. Bonuses are awarded for rescuing all of the graydians on a level, solving the mazes under a set time limit, or avoiding hordes of INKT enemies. de Blob is controlled by drawing or tapping on the screen.
