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: 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.
Revealing mistake: At the bar, when Zuse leans in to give Quorra a kiss on the cheek, his hair clips through the collar of his shirt.
