easy
yeah i only got hit like 2 or 3 times, but i guess that doesnt count as a full planet :( no mountains??? :(
it was really hard to maintain the planet though. i got plenty of clouds and atmosphere....
also I didnt get my completing the game medal, or the beating the game with no continues either... i guess it just didnt load?
its a decent game, but kinda hard and straight forward :/ fun, but not for long.
