level 6 really really easy
level 7 wasn't hard either, found both items, the random heart container and the triforce really easily without even getting one key. found the compass after killing the boss. now i'm mostly walking around in circles trying to figure out where i haven't been yet in the level, i can see the map, know how i'm supposed to get there, but can't find the missing key for the door.

seems like the map is the hardest thing to get in every level.
