It took me a minute to figure out I could navigate the rock faces that had markings. I was assuming those were blocked for some reason.
I enjoyed the challenge of the game. It wasn't too easy, but still winnable. Thanks for a great entry!
Oh yeah, actually you want to climb on them. They are "Cracked Rock" and is easier to climb. You use less energy when climbing it, and if you wait in cracked rock, it burns no energy.
