Save the Egg!
The first two levels were pretty easy to complete, but the third level introduced some challenges (a rock and an icehole) as well as fish. I earned bonus points for capturing the fish.
In the next levels, more father penguins started shuffling in front of me, a crevass or two decorated the ice, rocks got in the way, chicks started wobbling around the area, and a skua flew overhead repeatedly. Luckily, those obstacles didn't deter me from continually moving, keeping the egg on my feet and making the Egg'o'Meter climb to the red portion so that the egg could hatch. Lemme warn you: Level 13 was a turning point.
My score was 5810 at Level 20, when my mate arrived. Any takers?
