Dos game in <256 bytes
Code based on James David Chapmans' BD3, not that much of it remains.
Move man with csr keys, eat all jewels to open exit, don't let boulders
(or jewels) drop on your head! Shoving boulders sideways (if space beyond)
implemented. Space bar to restart level.

Uses int 21 for STDIN file read of cavern map, int 16 for kbd input.
Usage: BD<Caves.map

Version 2, now with a timer; much more exciting! up to 99s to complete
each level.

You must collect all jewels to open the Exit and get there before the
timer runs out. (it expires on rollover from 00 to 99, so 1 more sec than
on the clock, however you lose the 1st clock tick immediately).

Known Side-effects:
Can restart on most keys, (don't use tab).
Can shove boulders up as well as sideways.

Map "editing":

The top left corner of the Map holds the time limit - must be " nn''"
Need a char prior to the countdown number to set the colour
i.e. make it visible (it's a White Empty character). Also for the
timer to timeout the high digit must be in col2. col3 for the low digit,
next is the saved current second value (hidden) and then the
hardcoded position for the Jewelcount (also hidden).

If putting words in the header lines note that some letters will drop if
there are empty spaces below.
More than 1 player start position per map will crash the program.

Key to Map:
(space)=White Empty
!=Brown Earth
"=Cyan Block
#=White Boulder
$=Green Jewel
&=Closed Exit
%=Player's Start Position
'=hidden 0 (Empty)

Bah, and indeed Humbug.
