Hi HN,I challenged myself to build a multiplayer game in just 1 hour. My goal was to experience the distributed processing capabilities of Elixir and Phoenix LiveView firsthand by creating a simple web app.It allows everyone to see each other's cursors in real-time and fight a boss together. This is currently a beta version, and I plan to ship new features every week.It's deployed on Koyeb. I'd love to hear your feedback on the performance!
