| This level is hard!
This level is rather difficult. It can challenge veteran players and most beginners cannot finish this level. Most players consider it to be a hard level. Even elite players may have trouble beating this in one attempt. Good luck in beating this level!
(Note: Parts 8-16 of this tunnel can only be played with the Duplicator, so he will be the only recommended character.)
This level's ceiling, small platforms, and large numbers of crumbling tiles would make it hard enough as other characters, but the Duplicator? Good luck. By all means apart from falling off, avoid the Crumbling tiles, since by touching them, you are making the whole level much harder. The normal tile platforms are very small, and you need extreme reflexes and knowledge of the level to survive.
This level may seem very hard, but as long as you keep cool, experiment with the level, and use your duplicates to your advantage, you should be able to beat it.
