If you want to go in further, you'll need to take a harder test... Makes perfect sense, right? So what do you want? Do you want the new test?

Then go to Memory Lane 5 and defeat the Dodo. If you defeat Dodo, the giant Whale of Time that lives inside the temple, I will grant you permission to go beyond that.

That's too hard for you? That's too bad then. I guess that's just your limit.

As the representative of Rhinne, the Goddess of Time, I grant you permission to go past Frozen Past, the Door of Regret, to look at your 1st regret.

Go on. You should be able to go up till Road of Regrets 1. As you can guess, you can't go beyond that.

You've defeated Dodo. That's amazing. I will grant you permission as promised.
