It would be nice to have screenshots. Also it’s just a single commit, did you use AI? Quoting the readme: “FPS.cob is what you get when you decide that game development is too easy nowadays”.
As a few people have asked for screenshots, I spun it up. Here's a video of the basic gameplay: https://peterc.org/misc/fpscob.mp4 .. it's clunky, but it does play.
I had to get into an old tcl program for work recently and had the same thought. I wouldn't necessarily pick it today but it was kind of nice in a way that's unfamiliar to me from modern development.
If someone wants to have fun in COBOL, let them have fun in COBOL.
If it’s agentic fun, that’s cool. If it’s an interest in the language, that’s cool. It’s not like you have to have an ROI for a fun side project.

But tcl 7.x and before was a pure string-based language. Everything was essentially a eval(). People would hit syntax errors on production code.
Fun, painful times.
The flip side: the interpreter is super simple and fun to write.
