## Description
_Boulderland_ is a Boulder Dash clone. It supports keyboard and joystick
controls. There is an in-built editor, and a “replay” feature. Twenty standard
levels are included, but there is support for up to 999.
The main gameplay involves collecting a certain number of giant red gems and
then, when the right number has been collected, heading to the exit to
complete the level and move on to the next one, all within the time limit. You
use the cursor keys or the joystick to move, but if you move while holding
down the left shift key (or the joystick button), you can affect the tile in
that direction actually moving into that position. The main complication is
boulders: when each level starts the boulders are supported by the ground
underneath them, but as you dig through the level to get to the gems,
eventually you will need to dig directly underneath a boulder, leaving an
empty space underneath it. Since it is no longer supported by anything, it
will start to fall. If a falling boulder lands on you, you lose a life. You
can push a boulder left or right, but only if there is an empty space on the
other side, and only if it is not currently falling.
Then there are other game mechanics familiar to those who have played other
versions and variants of Boulder Dash: monsters that move around inside empty
space, and explode if you touch them, or a boulder falls on them; a self-
replicating amoeba that expands until it is completely trapped, then
transforms into gems; a type of magical wall that transforms falling boulders
into gems, if there is empty space underneath it; a wall with a gap that
closes up as you dig through it; and so on.
_Boulderland_ also adds some new mechanics of its own, such as bubbles that
you can burst (using numeric keys 4/8/6/2 for left/up/right/down) and bombs
that you can collect then deploy (also using the numeric keys).
