+Acid eats sand. Sometimes it spreads in all four directions, leaving a small
+explosion behind. If there is no sand to swallow, it just disappears.
--- /dev/null
+Another BD style amoeba, which behaves exactly like the other one.
+But it lives its own life. Sometimes, when they collide, they produce an
+explosion.
--- /dev/null
+Biters will eat all the dirt they can reach. They move in a predictable way.
+They can also eat diamonds, so better don't let them be taken away. They will
+move through rocks throwing them behind if there is no space for turning. That
+way, you can get rid of rocks blocking your way.
--- /dev/null
+This switch controls the speed of biters.
--- /dev/null
+Bladders can be pushed around easily. They slowly climb up; if they touch a
+voodoo doll, they convert into clocks. They can also pass slime.
--- /dev/null
+If there is space above it, the bladder spender turns to a bladder.
--- /dev/null
+You can pick up this bomb like a diamond. To use it, press the snap or drop
+key and a direction... and then quickly run away! You can hold only one bomb
+at a time.
--- /dev/null
+Sometimes you have to block a passage, for example to protect a voodoo doll.
+This is when a box like this comes handy. You can push it in every direction
+using the snap or drop key.
--- /dev/null
+A chasing rock looks like an ordinary rock. It can even pass slime. It is
+lightweight, you can push it at once, as long as it is sleeping. Once it begins
+to fall, it wakes up and begins chasing you. You can also push awakened rocks,
+if you have eaten the sweet.
--- /dev/null
+Collect this to get extra time.
--- /dev/null
+Conveyor belts will move around any object that can fall.
--- /dev/null
+This switch can be used to reverse the direction of conveyor belts.
--- /dev/null
+This switch turns the conveyor belts on or off.
--- /dev/null
+Covered tile.
--- /dev/null
+This creature wanders around the cave like a guard, but you can touch it.
+If it is enclosed, it turns into a skeleton.
--- /dev/null
+With this switch you can change the direction of creatures, like guards and
+butterflies. Sometimes it works automatically.
--- /dev/null
+Glued diamond.
--- /dev/null
+If you get this key, all doors will convert into diamonds you can collect.
--- /dev/null
+These creatures also guard the diamonds you would like to collect. But they
+move very differently. They like to run straight ahead, and only change
+direction if they bump into something. Like other enemies, you should not touch
+them. But you can easily crush them with rocks.
--- /dev/null
+After collecting the required number of diamonds, look for a flashing out box
+to exit the cave. Closed out box looks like steel wall, but beware of explosions
+near the out box: You could accidentally destroy an exit. This prevents you from
+successfully finishing the cave.
--- /dev/null
+Expandable wall, but made of steel. You cannot even blow it up!
--- /dev/null
+Expandable wall expands in horizontal or vertical (or both) direction, if there
+is an empty space to fill up. You should be very careful not to be catched by
+the expanding wall.
--- /dev/null
+With this switch you can control the direction of the expandable wall.
--- /dev/null
+Using this switch, you can control the direction of the expanding wall.
--- /dev/null
+Fake bonus.
--- /dev/null
+Whenever there is a falling wall above the player merely separated by empty
+space, it starts falling. It does so at any distance. If it hits the player,
+it explodes. If it hits anything else, it just stops.
--- /dev/null
+Exactly like a diamond, but instead of falling down, it flies upwards, as
+high as it can.
--- /dev/null
+The flying variant of a rock. Note that this one can crush enemies as well as
+the player!
--- /dev/null
+This is a door which can only be opened by the key of the same color.
--- /dev/null
+This is a ghost which wanders aimlessly. If it touches you, it will explode
+in an x-shape to many different elements.
--- /dev/null
+This is the gravestone for a dead voodoo doll.
--- /dev/null
+When this switch is active, you can use it to change the gravitation.
+The direction from which you use it will determine the direction the
+gravitation will change to.
--- /dev/null
+This is where the player enters a cave.
--- /dev/null
+This is also an exit, but it remains non-flashing and thus is difficult to find.
--- /dev/null
+There are three types of keys, which open three different colored doors.
+You can collect more from these; and for every door, always one key is used.
--- /dev/null
+Heavy elemenets sink into the lava and disappear without any trace left.
+Creatures can also step into the lava.
--- /dev/null
+Like an ordinary rock, but this one is so heavy that you cannot push it.
--- /dev/null
+Nitro pack.
--- /dev/null
+These nuts contain diamonds. If you crack them with a rock, they will be opened.
--- /dev/null
+This is the player. The player can move through empty space and sand, can pick
+up diamonds and push rocks, but should avoid fireflies and other enemies.
--- /dev/null
+Sometimes diamonds or keys are buried in walls. You can use a pneumatic hammer
+to break these walls, or simple walls which contain nothing. Stand on something,
+and press the snap or drop key together with a left or right direction key to
+use the hammer on a wall which is near the player, next to the element you
+stand on.
--- /dev/null
+Stir the pot, and you will be able to use the gravitation switch. While you are
+stirring the pot, there is no gravitation at all. Press fire after using the pot.
--- /dev/null
+This machine replicates the element which is on top of it. At regular intervals,
+a new element drops out underneath, if there is space to do this. The rate of
+materializing the new elements can be different in every cave.
--- /dev/null
+This turns the replicator on or off.
--- /dev/null
+Glued rock.
--- /dev/null
+You can move through sand, leaving empty space behind. Amoeba can eat it.
--- /dev/null
+A rolling ball of sand. You cannot push it, but you can dig it away.
--- /dev/null
+Glued sand.
--- /dev/null
+A falling piece of sand. You cannot push it, but you can dig it away.
--- /dev/null
+Acts like ordinary sand, but is sloped: Elements like rocks or diamonds
+will roll off to the left or right.
--- /dev/null
+Sometimes you have to collect skeletons before you can use the pot. In some
+other caves, they must be collected like diamonds to open the exit.
--- /dev/null
+Slime is permeable. It means that rocks and diamonds laying on the slime can
+randomly pass through.
--- /dev/null
+This is rock stable wall. It's impossible to move or blow it up.
--- /dev/null
+Acts like ordinary steel wall, but you can dig it away.
--- /dev/null
+Acts like ordinary steel wall, but can be removed by explosions.
--- /dev/null
+Acts like ordinary steel wall, but is sloped: Elements like rocks or diamonds
+will roll off to the left or right.
--- /dev/null
+This flying moth behaves just like a butterfly, except that it explodes into
+rocks instead of diamonds.
--- /dev/null
+Eat this sweet and you will become strong. You will be able to push rocks at
+once. You will also be able to push chasing rocks.
--- /dev/null
+The teleporter will move you from one place to another, if you step into it.
+The destination teleporter depends on the direction from which you stepped into
+the teleporter.
--- /dev/null
+Time penalty.
--- /dev/null
+This is an indestructible door with a diamond.
--- /dev/null
+This is your player's look-alike. You must protect it against flies. If a
+voodoo doll dies by one of them, your player also dies immediately. This doll
+can have different properties: Sometimes it can collect diamonds for you.
+Sometimes it must be protected from falling rocks. If it is hit by a rock, it
+turns into a gravestone surrounded by steel walls. Also, it may or may not turn
+into a gravestone by nearby explosions.
--- /dev/null
+Waiting rock.
--- /dev/null
+This wall contains a diamond which can be freed by using the pneumatic hammer.
--- /dev/null
+Acts like ordinary wall, but you can dig it away.
--- /dev/null
+This is a key enclosed by a wall. Use the hammer to break this wall and get
+the key.
--- /dev/null
+Acts like ordinary wall, but is sloped: Elements like rocks or diamonds
+will roll off to the left or right.
--- /dev/null
+Water, which floods all empty space slowly.
