On a serious note, nice job OP. This game kind of feels like an ASCII version of Terraria. Might I recommend extended ASCII or unicode for the player though? Right now they look a bit like a lollipop.

Writing any non-trivial video game with Rust is (arguably) interesting in itself since developer velocity in gamedev is generally considered paramount, and Rust has a reputation (rightly or wrongly) for hindering velocity.

So yes, the fact that this is written in Rust is actually relevant and valuable. As opposed to your hollow snark.

Now, OP: tell us more about how that's played out for you.
