AI Analysis

●●SolidNiche GemBold Bet

Bearing-only sensor tracking like a submarine sim — genuinely novel for browser space games.

Strengths

•Passive sensor mechanics (bearing → uncertainty circle → track) create real tactical depth.
•Rust+WASM+SpacetimeDB architecture enables live delta updates over websocket.
•Newtonian flight with no auto-brake demands actual piloting skill.

Weaknesses

•Landing page shows only loading screen — hard to evaluate actual gameplay.
•Browser multiplayer space sims exist (Starblast, etc.) with established player bases.

Post Description

Hi HN! I'm working on an open-world multiplayer space sim with submarine-warfare-inspired combat. Crew a ship, haul cargo, run heists, hunt your foes with passive and active sensors. Browser-based, free, no install.

Some of its features: - Submarine-style passive sensors. Contacts start as a bearing line (direction, no distance), resolve into an uncertainty circle, then into a full track. You triangulate over time by moving. - Silent running. Cut your emissions and witnesses can't ID you. - Newtonian flight. No drag, no auto-brake. Flip 180° and burn to stop. - Boarding combat. Dock with another ship and fight through it room by room.

Architecture: - The server is a single Rust module compiled to WASM, running inside SpacetimeDB. - Clients subscribe to rows in the schema and get live deltas over websocket; writes go through reducers (transactional Rust functions). No REST, no custom netcode, no client-side authority. - Client is Svelte 5 + plain HTML5 canvas 2D. No game engine, no WebGL.

Very early, plenty of rough edges. Would love to hear what breaks for you:
