I leave the 3rd dungeon and collect a couple of secrets on my way to the 4th dungeon buying arrows and food for the later dungeons.
Getting rid of the mini boss in the the 4th dungeon was a bit of a pain and the few rooms after I messed up with getting hit by the traps and enemies. The boss was pretty simple taking a few hits, but the mistakes I made weren't tragic in this segment.
