Played it! Wow, that was great! How did you do those chest-in-chest things?

I agree with Strike_. I have not tried the map, but you should make it so when the game detects the player has a certain amount of a certain item (or something like that), the border will expand (not too much or little, perhaps it would depend on task size), allowing you to explore more of the world!

does the wold border expand over time?
if not it should

intresting i will try it then comment
