Last night, when you were walking in the forest with your best friend, something attacked you and took away your friend. It was too dark, you couldn't see its face, but it wasn't human. It was some kind of Blue Color Beast. At first, you couldn't stand up from the shock. Finally, you pulled yourself together and decided to follow the monster and save your friend. Luckily, it was huge so there were a lot of broken branches and foot steps. You traced them to this point. It must be its home. It's surprisingly hard to get in. There are a lot of puzzles. Did I mention your best friend is a cat? Good luck!
