The cave painting in Spear Pillar is a puzzle, not an obstacle. You need to interact with it to progress.
Here's how to solve the cave painting puzzle:
1. Approach the painting. It's located in the first room of the Spear Pillar, on the wall to your left.
2. Examine it closely. You'll see three small holes on the painting.
3. Use the "Action" button (A button on most controllers) to interact with the painting. This will open a menu with three options:
* "Left": This will make the painting shift to the left.
* "Right": This will make the painting shift to the right.
* "Center": This will return the painting to its starting position.
4. Experiment with the different options. You need to align the three holes on the painting with three specific spots on the wall.
5. The correct alignment: You'll need to move the painting to the right once, and then to the left once. This should align the holes correctly.
6. Once the holes are aligned, the wall will disappear, revealing a secret passage.
That's it! You've solved the cave painting puzzle and can now proceed to the next area of the Spear Pillar.
