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 3 and defeat the Memory Guardian. If you defeat 999 of them, I will grant you permission to go beyond that.

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

You've defeated 999 Memory Guardian. That's amazing. I will grant you the permission as promised.

As a representative of Rhinne, the Goddes of Time, I now grant you permission to look back at your 4th memory.

Alright then. Go ahead. You should be able to make it all the way to Memory Lane 4. As you may have guessed, you won't be able to go beyond that. If you want to go further... you'll have to take a new test.
