Commander Keen Episode Four Secrets

Commander Keen Four is more advanced than the first three episodes, so it has more secrets and glitches.

If you hold down the keys B, A, and T, then you will get 99 shots, all four gems, and an extra Keen.
If you down the keys A, 2, and ENTER, then Debug Mode will be active. While in Debug mode, you can do secrets by holding F10 and various keys. I don't remember all of them, and they don't work under Windows 98 very well. F10 and G is god mode (you're invinsible). F10 and J is fly mode. F10 and N is No clipping, where you fall through the platforms. No Clipping an Fly make a good combination. If you fall through the bottom of the level, you die and get GOD mode turned off if it was on. F10 and Y make passages visible. F10 and I give you free items. F10-W lets you warp to any level.
In Sand Yego, there is a platform in an area with a slug. Turn off the platform while the slug is on it to give the slug a seizure.
In Border Village, to the left of the left slime pit, is a passage. Pogo into it to find a secret area with nine lives and another exit.
In Chasm Of Chills, jump from platform to platform. On the highest platform, pogo up high. You can land on top of the Chasm. Princess Lindsey is hidden behind a cloud up here.
Also in Chasm Of Chills, below the exit, is a passage leadig to a big secret area.
In Pyramid Of Mons, get to the room with the inchworms. Go to the far left of the room and pogo up by the wall. You should go through a passage and grap onto a pole. There is a little secret area above, along with another passage and two doors, one which leads to the top of the pyramid.
Also in Pyramid Of Mons, gather all the inchworms by you. A foot will appear and you can then jump in the foot to go to the secret level.
ALSO in Pyaramid Of Mons, stand on a moon ( they are on the gorund in some areas ) and wait. Instead of waiting, Keen will moon you! In Lifewater Oasis, try touching the top of the level(Fly helps). You will be teleported somewhere in the level, sometimes in the river with lifewater below the level.
If you save your game offscreen, you can restore it and see what was offscreen.
The secret revealed! Pogo backwards by jumping forward, then pressing backwards while in the air. While pressing backwards, you will momentarily still go forward. During this time, activate your pogo and you will go backwards! Wheee! Thanks to forge for this trick.
Hold down the keys E, N, and D to beat the game
