The concept is really good. I think I also used the same assets.
Going back in time and trying to find the needle in the haystack kinda of gameplay. I like the idea
The map was a bit hard to read in terms of direction but after I saw the very very small hints of gold dripping I finally got it.
I really love the "cant see your former self idea."
If I can suggest to build off the idea.
Maybe add levels where you need to achieve certain tasks that require you to visit more than once. like pull levers or take an object from one area to the next, to force the mechanic of avoiding your past self.
either way great demo. hope to see more soon.
