Loud Room Tester by K.V.

Quest 5 version of the Loud Room from ZORK 1.

After entering the Loud Room for the first time, it will move you to either the Round Room, the Damp Cave, or the Deep Canyon.

Upon re-entering the Loud Room, most of your commands will only echo. (Note: if you re-enter this time with commands in your queue (using multiple commands, separated by .), it will dump the command queue and tell you the commands were lost.)

Once you have entered ECHO or SAY, "ECHO" while in the Loud Room, things should normalize.
