In the game, the player assumes the role of Rascal armed with the Bubble Gun, in a mission through five worlds - Castle Hackalott (a medieval castle), Chichimeca Temple (an ancient Aztec temple), the aquatic city of Atlantis, The Jolly Raider (a pirate ship), and Dodgy City (a town in the Wild West).[3] Each world has three forms: past, present, and future[3] (e.g. Castle Hackalott appears as a medieval castle in the past while in the present day, it has become a museum). The player needs only to complete the past level to gain access to the next world. In each past and present level, the player has to find the six pieces of the Time Clock (some of which are held by certain enemies) in order to access the Time Bubble and complete the level, in turn unlocking the next form of that world. Each future level has a boss battle against Chronon and defeating him in all five gives access to the final world. The Bubble Gun has limited ammo, and the range and strength of the bubbles depends on how much ammo is left. In most levels, minor enemies will spawn from Time Bubbles over time (usually those to do with the level theming itself) and when defeated, they will leave behind various items such as Bubble Gun ammo (in either green or red; the latter can temporarily grant the bubbles with homing capabilities), hearts that will restore health and "Chronon's Gift" (a red skull and crossbones) which will cause damage to the player if picked up.
