"You control a ghost, the goal is to find the lock that opens the end of the level. You have to find keys to open locks. The potatoes are your enemies."
This is a fun but tricky little game. Control the ghost, avoid the potatoes (yes, potatoes, although I thought they looked like owls), pick up the keys and get to the locked doors. It's really quite addictive, although the baddies seem to have an uncanny ability to track you down within seconds.
