Score: 6.8/10 (Innovation: 6, Technical: 8, Documentation: 8, Utility: 5)

Zubspace is a browser-based remake of the 1997 online space shooter SubSpace, with a Rust-to-WebAssembly client and an authoritative Rust server communicating over WebRTC DataChannels with delta-encoded snapshots and client-side prediction. The project is technically ambitious for a hobby game resurrection, combining original game assets, zero-friction physics, and a 60-tick server with strong documentation on networking, physics, and server authority.

Target audience: game developers, Rust/WebAssembly enthusiasts, retro gaming fans
