Revealing mistake: At the beginning of any level, the lights are slightly transparent and the background can be seen through them.
Bug: Sometimes, if the player is hit towards a pole by a swinging hammer with a platform attached to it, they will clip through its support.
Other mistake: On the title screen, there are several mistakes. First, every splash screen has the stomping hammer facing backward. Second, while the obstacles and support change based on the country/region the level the player last selected is set in, the flooring and the background are always that of a USA level. In addition, after playing a Las Vegas or London level, the sides are that of a USA level as well.
Bug: If the player is crushed in midair, they will be floating.
Bug: When any object falls into the water, it is layered over it.
Bug: If the player returns to an area with flying boulders, they can go under them without being crushed, allowing them to clip through them.
Audio problem: The sounds for the air guitar, acrobatics, and football match will continue playing if the player leaves the courses where they play. If played consecutively, this can cause the sounds to end prematurely.
Bug: London 2: Blimey!: When you reach the part with the rolling obstacles, sometimes, there is an animation error where the first one does not appear to be rolling; it slides horizontally across its path until it reaches the end of it.
