WebRTC Challenges: My Experience Building FaceArena

Hey Product Hunt community!

Been diving deep into WebRTC recently for FaceArena, my online party game where facial expressions are the controller. The power of real-time communication directly in the browser is just incredible for creating unique, interactive experiences like this!

I'm curious: For those who've worked with WebRTC or built real-time features, what's been your biggest challenge or most surprising discovery? How did you ensure smooth, low-latency performance?

Would love to hear your insights!
