Other mistake: The description for the forest snow house reads, "An chillin' house for two Kefkimos." Since the article a precedes an indefinite word beginning with a constant sound with the article an preceding one with a vowel sound, it should read, "A chillin' house for two Kefkimos."
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.
Other mistake: When attacking an enemy with the spiked baseball bat, the weapon appears to hover a few inches away from the victim's head instead of making contact. Despite the clear gap between the bat and his skull, both the character and the weapon react as though the blow connected, with blood effects and animation playing normally.
