Commander Keen 4, 5 and 6 - the biggest secrets

Well, this is a video showing the secrets which IMO are the hardest to get of each game. Note that secret levels aren't included, because there are videos showing how to get them on youtube already. Also, I added 2 bonus tracks. The first one shows how the get the Standard Galactic Alphabet in Keen 6 (now you can decipher all the game signs hehe). The second one shows how to make Keen moon you in Keen 4. Enjoy and comment! Played by me :P

4. one can never play too much commander keen
5. lol, before I even clicked the link I knew the first one was going to be on here. Such a useful secret early in the game.
6. what the heck?! o.O
7. @zirkoni88 Indeed!
8. I knew these all already. Does that mean I have played too much Commander Keen?
9. Oi Oi this I have never known thanks for the tip;)
10. And I thought I knew these games... DAMNIT MY CHILDHOOD IS RUINED NOW
11. Hahaha, bad moon rising at the end!
12. Thanks a lot for the explanation, but as you can see, nettledog posted a video response so I already knew how to get this secret. But thanks anyway! :)
13. @Fernito69 you need to fall through the line of mines, theres a small gap right where the switch post is down there, but you need to be on the pogostick, its really hard to fall exactly on the right spot and once you do it you need to turn off the pogo immediately or you will hit your head on the mines, when you are through just go through the path down there and you will fall and appear at the top where all those stuff is
14. OK, nettledog showed me that I was wrong! It actually was a hidden door to reach the secret. Watch his video response :)
15. Judging by the "exit of some door" at the left, I'd say that they planned it as a "reachable" secret, but then forgot to put the door in. I don't know a level editor for KC4, but it should exist. I'll look for it :)
16. I'm 99.99% sure that it isn't possible to get that secret otherwise. I've looked for a hidden door thousands of times (even using cheats), but never found one.
