For part 1 my sneaky elves took a step north and then walked around the outside of the blizzard field. I trapped them in with additional walls \evil grin**

To be fair, compared to other years, only Elixir (last year) was more frustrating to learn than Rust (such that it does look like the picture above, due to many prototypes and all visualisation code being written in Python). I used Kotlin in 2020 and did Go for 2018 (though I didn't participate in that one live). I'm using C# this year, and all of these were simple enough that I didn't need to spend more time learning how to do things than actually doing them.

Plus Python visualisation

Python only today.
