on last level i got 8/9 and i cannot find the last one. i found the "hidden" one but this one is super hidden. help please!

Hello! I have found 6/7 skulls at the Sunny Coast, but the last one is eluding me. I had a look at a play-through on YouTube and the 7th skull on there is not in my game! Any tips? :)

Any plans to add them?

I only seem to be able to move around the map with an item in my hand. I have seen some of the secondary items, but I can't click on them because I have one of the primary items in my hand, and when I put the last one where it goes, the game ends without letting me look for the secondary items!?! Kind of frustrating....

Firstly, how cute is the singing at the title screen?! I enjoyed the demo, although I missed a feature to zoom in. It was ok, but not being able to zoom to see better doesn't seem very accessible, especially for people with smaller screens. I think it's also not possible to change the view, like move the camera? Do I really have to wander over the map to find secrets and the right spot for the piece?...
