R Key Level

This area can be found in H Level.

First area: use the collection of boxes to build platforms to allow you to get up the tall cliff on the right side. Double jumping may help.

Next you'll find a Red Gun and a box containing a Cyan Gunman. You can jump on the gun to demonstrate that the red gun will push and then discharge the box. Use the red gun to blow up the wall.

Next, three brick platforms that can be blown up with the red gun or the bombs in the boxes. You can also fire the red gun at the box near the same room collector to get a Silver Gem. Carry on down and left.

Next, a collection of 7-second bombs, an ice box and a blue-yellow laser. The laser will kill anyone that touches it but you can shuttle items back and forth by sliding the ice box. Use two of the bombs to blow up the brick barriers. Continue down.

Next, you'll find a Heart (health restore) and a red gun. In the next room there are some electric enemies and boxes, one of which contains another heart. Another box you can fire into save room collector containing a Silver Gem.
