APL is sufficiently different to Rust that a direct port is less viable
Rust programs usually have very deep dependency hierarchies, a gamedev project can legit have 500+ dependencies. It makes no sense to port them individually (though maybe LLMs actually make this dumb approach viable)
APL programming.. isn't like that. It isn't just a different language, it has a different shape
Rust and Javascript are interchangeable in some domains (and not interchangeable in others). You can convert between them more or less automatically
But APL? You would need some taste to implement in APL what the game needs, even if the actual coding is done by a LLM
