The USA release of Zero the Kamikaze Squirrel shares the same basic premise as the European version but might have alterations to suit the American market. This could include changes in language, content, or even gameplay mechanics.  The developer and publisher would require additional research. The core gameplay remains the platforming adventure centered around the squirrel, Zero.
