That's not even a recreation, it's just the leaked sources of the game recompiled to WASM, so I don't think their prompt would apply to this case.

I tried locally and Opus was willing to go ahead to rewrite a decompiled game into Rust. Wording changes its decisions a lot, when I say "rewrite it in Rust" it proceeds, when I say "recreate it in Rust" it refuses, probably because the prompt uses "recreation"
