Hey! Very cool! What inspired you to create this in Rust? Also, you should message @redblobgames on the procjam discord. He is very into this type of proc gen. You will probably love his stuff as well, if you haven't seen it already: https://www.redblobgames.com/
Sorry for the very late reply (I don't check itch.io often, and I didn't check the mail adress I'm using for itch.io for a while). I'm already on the procjam discord for several months, so I know about @redblobgames.
Why Rust ? I wanted to try Rust for a while, so I took the opportunity of the jam to do it. I already coded map generators with some similitudes to this one, so this was more about testing Rust. However, I also wanted to check the complexity of writing that generator, to check if it could be done in coding dojos.
