Elsewhere - A flight simulator for places that don't exist.

Elsewhere is a calm, open-ended flight experience for exploring places that don’t exist. Fly a bush plane or light jet through endless procedural mountains, islands, coastlines, clouds, weather, and changing light. No missions, scores, or marked destinations - just follow your curiosity.

Hi Product Hunt! I’m launching Elsewhere: a flight simulator for places that don’t exist.

You get a small aircraft, an endless sky, and absolutely nowhere to be. The world keeps unfolding around you: mountains, islands, coastlines, valleys, cloud layers, weather, and changing light. If something looks interesting, that is the destination.

I built Elsewhere as part of the GPT-6 Astra Challenge. Astra was used as a building partner across the engineering, procedural generation, visual direction, flight model, audio, testing, and iteration - not as a chat window placed inside the product.

A particularly fun part of the process was connecting Astra to Blender through MCP: we used that bridge to iterate on low-poly trees, rocks, landmarks, boats, docks, and atmosphere, then exported a reviewed asset kit into the browser with explicit placement and validation rules. The finished experience is deployed with OpenAI Sites, so the result is directly playable in the browser.

The result is intentionally a little unusual: a game about wanting to go somewhere, without ever telling you where to go.

I’d love feedback on the feeling of flight, the world generation, and the first place you found yourself flying toward.

How did Astra change the scope or ambition of what you built?

Astra expanded Elsewhere from a simple flight prototype into a complete, authored world. It helped me iterate across the flight model, procedural terrain, lighting, atmosphere, foliage, landmarks, audio, and visual QA. Connecting Astra to Blender through MCP also made it practical to create and refine a cohesive low-poly asset library, then bring those assets into the browser with placement rules and performance constraints. Without Astra, I would have built a much smaller flying demo; with it, I could pursue the more ambitious idea of an endless, explorable world with its own visual language and sense of place. The live product is deployed with OpenAI Sites, making the finished browser experience directly shareable as part of the challenge submission.
