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!

Please add screenshots or even a gif. Some of us are curious but not so curious to jump in to see the action.

That's a great point. I'll update the post with a demo GIF soon so you can check it out easily without running it.

seems overloaded, also seems to behave oddly.. seems like it got overloaded, slowed to a halt, lost a lot of progress and got switched into the kr region?

Thanks for the feedback! Since this is a side project, I'm currently running it on a free hosting platform based in the Japan region. That's likely why it felt overloaded or slow if you are connecting from the US or Europe.

I’m also aware of some weird optimization bugs where the game lags or drops frames on non-Chrome browsers and Linux (Ubuntu). I'm still looking into why this is happening.

Sorry for the lost progress and the lag! I appreciate your patience.
