In the browser

Walk it yourself.

This is the build from the prompt above, running live: a rain-soaked harbour at night, three word stones, one housekeeper, two ways to end the sentence.

One line in. A level out.

Neta Studio reads the place you describe and builds the thing itself — geometry, light, a camera, a character who belongs there. You steer it in the browser, fix what is wrong in the next sentence, and publish a link that opens on a phone.

A level, not a mockup

Real geometry you walk through with WASD or a thumb pad, under a camera you drag.

A character with a name and a line

The person in the level speaks when you finish the objective, and remembers which reply you picked.

A link you can send

Every build publishes as a playable page — no export, no engine, no build step.

Questions, answered.

Do I need to know a game engine?

No. There is no engine to install or learn: describe the level and it is built as a playable page.

What do I actually get?

A published link to a browser-playable 3D game with a level, three things to find, one conversation and an ending.

How long is one level?

Two to four minutes to walk and find three things, then a short exchange and an ending card.

Can the character look like someone?

Yes — describe hair, clothes and colours, or name a character from a world you already built.

Does it work on a phone?

Yes. The same link opens with a thumb pad to walk and drag to look around.

Can I change it after the first build?

Send the next sentence: move a landmark, add a character, rewrite the ending. Each pass keeps the level.

What can’t it do yet?

It builds one compact level, not an open world: expect a short scene, a handful of props and one conversation.

Can I share the game?

The link is public and playable. Send it, embed it, or keep building on the same world.

Start with one place.

A harbour in the rain, a school roof at four, a lobby with a flag on the wall. Pick one and walk it.
