Wow, 21 years since Keen was released! I loved making those games. The first games we made for a pure love of gaming.
One tidbit on this anniversary: the “swear word” in the one level of Keen was actually deliberately misspelled! Just a dumb joke that people who found it would assume what it was, then be wrong at the last letter. Sort of like the tiles drawn out of the Scrabble bag in Hitchhikers. 🙂 Always knew there was something fundamentally wrong with the universe.
Anyway, happy birthday, dude!

Happy birthday Billy!
Even now the Keen games are lots of fun, and still very playable.
I don’t think I ever read/heard the misspelling was on purpose, so it’s nice to find out.

After all that time it’s still one of the best platformers on the PC. I salute you, Keen! May your rayguns be charged plentifully.

Keen was awesome as well as other games that followed.

And after all that time, it is still one of my favorite video games ever. I miss Keen!

My favourite game ever. I always feel so sad when I think about how its story was never finished… Is there a subtle chance of doing it someday, Tom? I wonder how bad that rights mess with iD is

I was browsing through SDL games at libsdl.org and came across this. Seems like there is some open source work going on and keeping keen alive! http://clonekeenplus.sourceforge.net

Notch seems eager to throw money around lately, and there’s a bit of a market for retro platformers these days. A bit late to hit Christmas ’92, but how about Christmas ’12? Eh? Eh?
