BE Creative Puzzle

Game Rules

This game seems like SoulManager and Notpr0n, but in fact it's totally different.
This is not a "one-level-one-picture" game (some level doesn't have any picture and some has more than one), and never needs any username/password to reach the next level. All you need is to find out the URL for next level (same as usual).
CREATIVE is the keyword of this game.
You must be more and more creative to go deep inside this game.

Game Features

1. Each level has a difficulty meter (1-100) to indicate difficulty.
2. Each level has a code (like SoulManager), you need them every 10 levels.
3. This game can never be incredible hard (even 100 difficulty, not like notpron).

Attentions

1. Do not tell others the solution of levels, that will be no interesting.
2. The codes will be changed by time to prevent cheating.

Enjoy the game, have fun!
