Voyage (UP)

Story related, can't be missed. After reaching the pains, using the cow to knock down the huge obelisk, and making your way down to the beach, you will enter a craft of some kind. You will be transported and have to do another statue pushing section. Once this is done, your achievement will unlock.

The game is very simple so shouldn't give you much trouble. Just keep moving to the right, using for hints for anything you may need to interact with (with ).
