One morning, as you wake up, you feel something on your face: It's a letter. As you take it off your face to read it, You fall off your bed. Uurrrgh, you say and stand up. The letter says:
&$t |* }p|t Hmmm. Seems angry.
Meet me at 8th and main st. behind the post office in half an hour. Be there. From Yout Ried. Ok, you think.
On the wall you read:
Say the code and escape. You have 3 tries.
Just beneath that you read:
wco ard_q'r uigv wywqwxx wwv kmill, z xvhqigx. rvczym, _h_l nrz. ohlnmv lq: smlvvg_
The angry message isn't really angry...
The rulebook for Kandoodle might be of help...
What you can decrypt from the clue will fill the blank spaces on the message on the wall.
If you can't figure out what the letter means, look up rot13 cyrptii and fiddle with settings.
