One lane is a room in a much bigger world.

Neta Studio is an AI world builder: one sentence becomes a world with characters, maps, art and playable games. A cat defense game is one shape that world can take — tonight the cast holds a lane, tomorrow the same cats walk into a roleplay or a sequel.

Cats with different jobs — one swipes, one bursts, one slows, one reaches across the lane. Four answers, not four reskins.
Waves you can tune — enemy counts, health and spacing are data. Ask for a harder wave 8 and only that wave changes.
A run with stakes — lives, a vault, a win screen and a lose screen, so a wave can actually be lost.

Questions? Answered.

Do I have to code or draw the cats?

No. Describe the cats, the thing they guard and what attacks it. You get a game screen with pads, waves, gold and an upgrade panel, and you play it in the browser.

How does a wave actually play?

Mice walk one lane toward the vault. You place cats on pads beside the lane, each with its own attack. Kills pay gold, gold buys more cats and upgrades, leaks cost lives. Clear eight waves and you win.

Can the cats be characters from a world I already built?

Yes. Build the world first and the cast carries over. The three games on this page were made inside existing worlds — Horimiya, Genshin Impact and One Piece — with the defenders named after their casts.

What builds it?

The Game Maker skill inside Neta Studio, the same path the button on this page uses. It plans the loop, builds the page and the art, publishes it, then checks that the wave loop really runs.

Can I make it harder or easier after playing?

Yes, and only where you ask. Ask for slower mice, more starting gold or a boss with more health and that value changes; the rest of the build stays as it was.

Does it work on a phone?

Yes. The board fits the screen, the pads are thumb-sized and the cat cards sit along the bottom. No scrolling to reach the lane.

Can I share the finished game?

Publish it from the world and send the link. It opens in a browser with nothing to install — all three games on this page play that way.

What should I type in the box?

One sentence with cats, a place and a threat: “raccoons raid a bakery at 3 a.m., held by three bakery cats”. That is enough to start.

Give the cats a lane to hold.

One sentence about the cats, what they guard and what's coming. The pads, waves and upgrade panel come back with it.
