Commander Keen, boy how I remember this game from my childhood. It was great fun, and to this day, I still play it from time to time.

Therefore, I’m gonna let you try it. Have fun! (click the image after the break)

If you have some problems, try running it using this guide.

PS. I’m gonna have a few more of these in the following week - keep an eye out.

(I got this game from http://commander-keen.com, my personal copy is MIA)
