Commander Keen 1 Gold Level 6 map


Today I started making map of Commander Keen 1 fanmade mod Keen 1 Gold Edition can I finish this map which I want to show you?I just to ask for a permission because I’m just wondering who owns the licence of Commander Keen nowadays is it 3D Realms or Besthesda Softworks because if someone played Doom(2016)I guess someone noticed Billy Blaze’s helmet cameo easter egg.I’m asking because I don’t want to get lawsuited.I hope you will allow me to finish this map I’ll post you a screenshot,okay.Good news European Parliament rejected new copyright law,but I heard only temporarily.If you wish to stop making this map at next time I will listen and I swear that I won’t do it.
