You're right, that would have been cool. I really like Moon Zone 9 so far, though there is some discrepancy on the length of a Lunar day. One section says 28.5 Earth days, the other cites the Moon "day" as 14 hours.
Wiki Answers says: The length of day on moon is (27.32 EARTH DAYS)
27.32 days is the length of a sidereal day.
The length of a lunar solar day (the time it takes the sun to appear in the same spot overhead) is 29.5 days. This is because as the moon turns, it also travels along its orbit about the sun.
