Hi Product Hunt! Doeon here, one of the 2 people behind Zero. A bit of context: I'd never built a game before. Last year I posted Ask HN looking for game-dev resources (https://news.ycombinator.com/ite...), and 140+ developers wrote back. A lot of what we shipped traces back to that thread. Six months ago we started. Today Zero runs in four places: browser (https://0.space), iPhone, and a very early desktop beta on macOS and Windows. One Rust voxel engine across all four, same world byte-for-byte on every device. We just finished the C++ to Rust migration. Heads-up on desktop: it's a very early beta. Expect bugs. If you try the macOS or Windows build and hit something (crash, install, sync, anything), please drop a comment here. Bug reports from this stage really help. Today: cubic brushes (Minecraft-style block stacking), real-time multiplayer, instant join. Coming soon: a smooth-curve sphere brush that uses dual-contouring under the hood. One thing to be upfront about: core game mechanics are intentionally thin right now. The first 6 months went into validating the technical foundation. The mechanics layer (gameplay loops, progression, deeper in-world systems) is what we're building next. Two of us. Still early. Would love to hear what you think :)
