## Original post

I vibe-coded a GTA-style open-world game that runs in the browser (alpha, feedback welcome)

Hey, I'm Louis, 18. For the past while I've been building a GTA-inspired sandbox game that runs entirely in the browser, no download. It's an alpha, so it's rough in places, but it's somewhat playable. Play it here: https://wta.lou15.com What's in it: an old-town map, driving, and a city to wander around. Still working on more. I built it with Opus 5.5 using Claude Code besides school, so I'd love to know what feels off, what breaks, and what you'd add next. Any feedback is welcome, even a one-liner. https://reddit.com/link/1x70rmy/video/r7ia5jqgwpvh1/player   submitted by   /u/LuckyTNTyt   to   r/SideProject [link]   [comments]
