The next few levels won't be as annoying as the previous ones. You'll have to solve riddles (you will be told the riddle after entering each level).
See that shiny light in front of me? You'll have to find a certain one throughout the level. When you walk close to each of them, a time will be displayed (such as "1 o'clock"). You'll have to choose 1 or 2 of these times to answer the riddle, then head to the exit. If you are wrong, you will not be able to head to the next level, and your selection will be reset so you can try again.
Answer: 6 o'clock
The right time(s) for this level is the times which can be interchangeable when they are upside down.
Answer: 9 and 6 o'clock
The right time(s) for this level is the times when we use as prepositions in English.
Answer: 4 and 2 o'clock (remember "to" and "for")
The right time(s) for this level is the time that contains a triangle.
Answer: 4 o'clock
Lv55) The next boss is very, very hard >->
The moment I walked into the boss field, my MP was drained to 0 and a few seconds later, I got a hit that was about 20k. Instant death x.x
Fortunately, I found a ninja that helped me with Ifrit. This boss is definitely for ninjas, or anyone with HP or good evasion. Definitely not for a high wizard.
The next few levels you have to walk through will be very easy compared to previous ones. No hidden tricks, all you'll have to do is walk around a few waterfalls.
Lv60) Here you'll meet the Lv203 boss Echidna (actually a nice looking boss). She's was a fairly easy solo for me, but she causes a lot of status ailments. There's also a really annoying skill delay increase for a small amount of the battle. Darkness is her weakness.
Level 60 is the last floor that has been implemented as of recently. When you try to go to the next level, you will be "pushed back by a mysterious force", and given the option to stay where you are, or leave the maze.
