*note 1:- You should see the message "You hear a huge bang.The cave shakes" appear round about now. It is triggered after the tenth turn. This event is needed to enter the location "In a huge room" without instantly getting killed by "Bruce" the NPC.
Bugs:-
There is a bug with the "wait" command where it actually waits two turns instead of one. This can cause the "cave shakes" event to be skipped altogether, making the game impossible to complete. So it’s best to avoid using the "wait" command before this event occurs. In fact it is not needed to complete the game anyway.
The matches are not actually needed to burn the log. Although the player may have the torch, its description on examination reads “It is a pen torch,already lit". As a pen torch is not a combustible torch, this means the player can burn the log without being in possession of an obvious item that can start a fire.
On attempting to move the boulder without the crowbar, the intended response "You strain but it doesn't budge" is never shown. This can be fixed by changing ol(7)=1 to ol(7)=l on line 790.
In location "by a large hole", you do not need to wear the shoes to avoid
falling down the hole, simply having them in your possession is enough. However only when the shoes are worn will you see the message "The oversised shoes stop you from falling down!" (sic).
In "rocky cave", "throw dynamite" blows the wall into rubble (needed to escape the caves), but there is no wall object present nor mentioned in the room description.
