Tresure cave How to "escape"

I get the coins but how do you ‘‘escape’’

You have to go back to camp.

Technically there should appear a white x-mark in the camp once you got all coins.

Oh back to camp gotcha!

No point waiting in the cave for the yeti to return, right?

It doesn’t really look like a cave

I was promised a Yeti-Cave, but the graphics are not finished yet. Until then, this is the best I could do. And this cave has a roof, I just decided to not include it in the level so the player can see the action inside the cave.

Could you start with the roof, then rip it off???
