There is a big bug in this game.
In cave K level 5 , there is a missing diamond.
You must collect 27 diamonds while there are only 26 diamonds.
Is there any .ldr file or a cheat that allows us to choose all of the caves from A to P and at any level from 1-5?
Btw I have finished boulderdash 1 and opened up all of the caves and at every level.
