You play as Mumu, friendly yellow squirrel who is looking forward to an
evening with his beloved Fufu. However you will have to eat all the fruit in
the area before she will show up. Normally this would not be difficult, but an
owl by the name of Fukurou lives in these woods. Now we all know the relation
predator/prey relationship between Owls and squirrels….

You move by pushing the left and right arrow keys and jump with the space bar.
Jumping into the air and hitting a food will count as eating it. Fukurou will
occasionally wake from his sleeping spot (on the leftmost tree) and try to
catch you.You will have to jump on his head and be flown up to get fruit
higher than your jump will reach. The owl is not, however, agreeable and will
try to shake you off.
