I've worked in Erlang/Elixir for the past few years and I haven't had the opportunity to work "in anger"[0] with languages with traditional threads/mutexes/sempahores. This game was a blast and made me appreciate the Erlang's approach to concurrency. The best beginner resouce I've read on Erlang's concurrency model is here https://learnyousomeerlang.com/the-hitchhikers-guide-to-conc...
