The alphabet

In this Game, you are in the infinite maze full of different rooms. 

Every doors to the room has a sign on it saying what’s inside.

But words on the doors are encrypted, you will see a bunch of numbers. Each number from 1 to 999 represents a letter.

Your goal in this game is to fill in your notebook with all the numbers for specific letters.

For Example: if the text on doors is 920 401 64  53 185, you open those doors and there is only a chair in the room, you can assume that code for c is 920, h is 401, a is 64, i is 53 and r is 185.

Open your notebook with N key on your keyboard and fill in those numbers

However, not all the letters can be found in room names, some of the codes are written on signs that are hidden in different rooms
