I remember you showing me this! Wow that was a long time ago.

I love that language and frequently show it to people. I'm sad to see that my local install doesn't work any more. I actually used it to solve a puzzle in Evoland 2 that I'm relatively sure was added as a joke, and is not solvable in a reasonable time without a solver. I'm actually doing a PhD in compilers right now, and would love to chat about sentient if you have the time. My email is [email protected].

You might be interested in looking at MiniZinc (https://minizinc.org/) which is an open source modelling language for combinatorial problems. The system comes from a constraint programming background but the language is solver agnostic can be used to compile into many different types of solvers.
