Stuck on lvl 12

[Guest oddjob]

I've arrived at 12, what do I do now? I kill hyenas and they seem to regen, is there an end to this? Also, all I see is a broken generator, a broken rail bridge, and a stone I can pull out a bit from one pyramid, but I can't get in. What should I do?

One advice,

 

Climb the pyramid.

[Guest Squint Grimjaw]

Keep running those hyenas over. You'll eventually receive a musical cue to let you know all those 4-legged bitches are sand mulch. Fun ain't it.

Then you are going to climb the one side of the pyramid the little Unicef kid hid in.

This level rules!
