Awesome game, the art is really nice, the music is impressive for a first time and I really like the moving objects to reveal the hidden items.
I have some feedback if that's okay:
I think you misspelled "them" as "then" on the itch page (fourth bullet point).
I see you already got the feedback on the objects being above the border but maybe I can give some pointers to help with that. In godot the nodes at the bottom of the tree are in the front by default, so maybe just moving the border node up a bit might work. For visuals there is also the z index in the node properties under canvas item->ordering higher moves items in the foreground so you can also order the layers like that.
The camera sticks to the borders a bit, like if you walk offscreen and have to return first before you can move away from the border again.
There is a bug (pictures) when you finish the game, go back to the menu and then reset the game with the button at the top some unexpected things happen:
The you found everything button is still there but you can play the game again.
When you go back to the main menu two songs play above each other.
Finally when you then reset the game from the main menu you can finish the game by just collecting five items.
