How do you create these puzzles? Even a computer couldn't solve it. (For the record I checked after I did the puzzle.)
"The Last Teenager" Puzzle

Champ, your compliment is humbling me, yet very heart warming. Thank you ,so, so much!
In reality, I had not made a decent puzzle in long, long, long, time to a point I was thinking that I was done for good. I made many attempts and it really was not going to be. However yesterday it all came into place. And there it is. Of course there is a small detail that would have made it better if that rook on g6 was not there at the end of the puzzle. So who knows?
Much obliged to our friend NM @kracker12345
Salutes! 
Generally in checkmate problems the extra material doesn't matter in the final position but here it stings because "Rg6" is the only unit that disturbs the perfect model mate! So you are right about your wish to remove it. Not easy to accomplish though I guess.

Master you hit the nail spot on. Not easy at all... 
Dear Raccoon thank you for your kindness. It takes a smart kind-a "Kit" to see the "lit", my friend.
