I noticed that this dungeon is lacking in a couple of things.
1) No yum yum fruit, at all. When doing 4-5 battles back to back, it is a bit essential to have some way to regenerate yourself. I was finding myself severely low on health after every battle so I used my potions, all 2 of them. After the 3rd battle, I was stuck.
2) I headed back toward the earlier rooms in the crypt to see if I happened to miss any yum yum fruit and found myself outside without warning. There is a warning that you are entering a dungeon, but nothing that you may be leaving one. Now, I have to start all over again.
Please, look into this and adjust these few things. Thanks.
