To explain myself on the 'Heart' level; there is a point where you land in a room with 3 paths to choose from (and only one if no boomerang, which is possible). One choice is very bad, and leads you back out the "hard way". One choice is good, although you wouldn't know it except that I don't lock you in the room. The third choice is mediocre. It can get you where you want to go, but most likely it will just dump you back out of the level also. The "good" path is what I should work on, to make it more obvious.

When you near the item, it does get a bit easier. Probably too many Baby Dodongos there; although I did not find them to be too hard once i learned the trick to beating them (let them rush you, but dodge and kill when they reset). Currently they have the Rupees item drop set-- perhaps they should have Life instead?
