Commander Keen 5 Easter Egg - Engineer's Name

One of the game engineer's name is located in "Energy Flow Systems."
First you go to Energy Flow Systems and go as far down as you can on the right. Where you have to put the yellow jem. Find it and put it in or type TAB simulateously. And open the door and go as far right as you can and jump up with holding the right arrow. You will go to a secret and below you there will be one of the Game engineers' name!

PS: there is an extra life to the left!
