Show HN: I hated how much my 12-year-old played Roblox, so we built our own FPS

I'm a father of two, 7 and 12. They are obsessed with Roblox, especially Rivals. Like a lot of parents, we did not love it. We tried the usual things: block it, limit it, set timers." It became a daily battle, a lose-lose situation. So I flipped the problem. Instead of fighting what they loved, I decided to lean into it, but with a twist. Why just play an FPS when you could build one together? My kids became the PMs. Claude and I became their engineer. I was shocked by how fast we moved. We picked a name, Cooked and started building. Get in. Lock in. Get cooked! In the first 3 hours, we had an actual FPS we could play together in the browser. Next day I invited my friend's two kids over.

It handles presence and the WebRTC handshake. - It is very cheap to run. Static site plus a few Cloudflare edge functions for TURN relay. - Bots fill empty rooms. Each bot gets a random loadout and play style. # What worked and what didn't I have been writing software for 20 years. For the last 9 years, as CEO of Krisp.ai, I have not had much time to program myself. I missed it. Claude changed it. I obsessed with this side project for the last 2-3 weeks. First, building a project with your kids is a great way to bond. It gives you shared inte
