I haven't played a Commander Keen game since I found his dead body in a secret room and was scarred for life at age 11 or 12. I'd be down to try a new relaunch or remake or even a perfect port.
You forgot to mention why they made Keen. They made a supposedly perfect PC port of Super Mario Bros. 3, and asked Nintendo if they could put it out with them. Nintendo said "Hell naw hell naw" so id turned it into Commander Keen.
