Commander Keen: defender of the Earth!

Commander Keen 1 on Windows 10.

Billy Blaze, eight year old genius, has created an interstellar spaceship from old soup cans and transforms into Commander Keen, defender of the Earth! Classic side scroller, developed by John Carmack and John Romero, also known for Wolfenstein 3D, Doom and Quake. Their developing adventure started with Commander Keen, which should have been a PC port of Super Mario Bros 3. Thank heavens Nintendo said "no". If you have the game, you can of course play it with DOSBox. If you don't have it, you can download it from Steam. Or you can read on.
