ELEMENTS & ITEMS

SCORE MULTIPLIER

The score multiplier kicks in when you kill an enemy and continues to rise with additional kills. While active, your score will be multiplied by the number displayed. The time you keep the multiplier is limited (about 10 seconds) so act fast to get the combo as high as possible!

WALLS

Ordinary Walls are the static structures that help define caves.

Neither Rockford™ nor Crystal™ can pass through them. They have rounded corners, which explains why boulders sometimes roll off of them. Ordinary Walls are destroyed by explosions.

TITANIUM WALLS

Titanium walls are indestructible and look different from ordinary walls.

DIRT

Dig dirt to clear your path by simply walking through it, or by using the “Push/Grab/ Dig without moving” command. Boulders will not roll off of dirt.

DIAMONDS

Diamonds are collected by walking through them. When you’ve collected enough of them, the cave’s exit will open. Diamonds fall just like Boulders. They crush enemies but not you, except in Retro Mode where they do!

BOULDERS

Falling Boulders are lethal! Walk up to a boulder and push against it to move it left or right; or, use the “Push/Grab/Dig without moving” command. When perched on top of Diamonds, other Boulders or certain Walls, Boulders will roll off. Crush enemies with falling Boulders to increase your score!

HEAVY BOULDERS

Heavy Boulders act the same as regular Boulders but are too heavy to push. Use the Telescopic Arm to move them with ease!

ENERGY BONUS

Collect this to fully restore your energy. Isn’t it great being a robot?

SPEED BOOST

This greatly increases your speed for a short time.

BONUS TIME

Need more time? Keep a look out for this essential item!

TELESCOPIC ARM CHARGER

The charger allows you to use the Telescopic Arm once. The charger will reappear after a short while, so extend that arm as much as possible!

KEYS AND DOORS

Keys come in three colors, and each Key opens all doors matching its color. Look at the bottom screen to see which Keys you’re currently holding

TELEPORTER

Step right in to be transported to another Teleporter of the same color.

ONE WAY DOOR

Once you pass through to the other side, there’s no coming back! However, you can stand in this Doorway.

DYNAMITE & DETONATOR

TNT can be pushed and moved without exploding. When you’re ready, use the Detonator to blow up all of the Dynamite in the cave, destroying most nearby items.

MAGIC MACHINE

When Boulders fall into this machine, they turn into Diamonds! Unfortunately, it also turns Diamonds into Boulders. The machine won’t work if something is directly underneath it.

EXPANDING WALL

Only found in certain Retro caves, it looks like an ordinary wall, but starts expanding when nothing is blocking it. Be careful not to get trapped!

MAGIC WALLS

Like the Magic Machine in Arcade Mode, Magic Walls in Retro Mode convert Boulders into Diamonds or visa versa. Be sure to clear space below the Magic Wall and act quickly ….  these turn off after a while and can only be activated once in any play session.
