Loot Hole is live: using AI to build a browser game, then testing the parts it got wrong

I'm making Loot Hole, a free browser game about digging up treasure, selling your finds, and upgrading your shovel. It started with Babylon Lite and WebGPU. We moved to three.js, then built shared gameplay in Rust with wgpu for native platforms, and brought three.js back for the web. AI helped with implementation, but testing on an older Galaxy A40 shaped the architecture. Keeping the web renderer small mattered because players should get into the yard quickly. The browser now runs the Rust game core through WASM, with three.js and DOM presentation. Native builds keep wgpu. A specific example of the AI workflow: Claude Code helped implement and test fixes for our Rust Opus decoder. We compared all 64 game sound effects against libopus and traced short glitches to decoder state transitions. That work produced four opus-rs PRs with focused regression tests. They are still open; I'm not claiming those fixes have been merged upstream. One is here:…
