## Description
_Rockfall_ is a Boulder Dash clone written in 68000 assembler where you on
every level (there is a total of 48 levels in the game) have to collect all
the diamonds before the time runs out. Be careful of boulders because they
will only stay still on flat surfaces and once they fall you cannot out run
them. At later levels monsters and pulsators will start to appear. There can
be up to 4 of each in a level. Both monsters and pulsators has to be disposed
of in one way or another. Monsters walks randomly in the level while pulsators
always follows the walls and they will always turn left if they have to choose
direction. Monsters can be killed using boulders while you need to use traps
to kill pulsators.
At the start of the game you have 180 seconds to complete the first level. For
following levels, you get an extra 120 seconds in addition to what you have
left from the previous level. If the timer reaches zero it’s game over.
