Show HN: Codebattle – game for coders

Hi all, my team and I develop a platform for in-browser programming lessons in the real dev environment. It's like Codecademy, but on steroids (real docker containers, web IDE, root access, etc; more info here https://en.hexlet.io/).

As a side project, we've created a game for coders called Codebattle. Pick a language, create a game, when opponent joins — you're both given a problem to solve. You can see each other's code in real time. Whoever solves the problem first wins. There are also spectators and a chat.

This is still an early beta, any feedback is greatly appreciated. Languages available at the moment: Clojure, Java, Ruby, Javascript, Python, PHP, Erlang.
