Build a Browser Game with an AI Editor
A browser game is just a web page that responds to input. That makes it a wonderful first project for an AI editor: you see results immediately, and the code is plain HTML, CSS and JavaScript you can read and change. Here is a path from idea to playable link.
Pick a tiny game
Choose a rule set you can describe in two sentences. "Click the falling stars before they reach the ground. Each catch scores a point and the stars get faster." Small games finish quickly and are fun to share.
Describe the loop
Every game has a loop: something appears, the player acts, the score changes. In SiteSim, write that loop plainly, including the controls (mouse, touch or keyboard) and the goal. Mention that it should work on phones so touch input is included from the start.
Play the first version
The preview runs the game live. Play for a minute and notice what feels off. Is it too slow? Are the targets too small? Those observations become your next prompts.
Tune with simple requests
- "Make the stars twice as big on small screens."
- "Add a score display at the top and a restart button after the game ends."
- "Increase the speed a little every ten points."
- "Play a short sound when a star is caught."
Adjust values in code
Open the JavaScript and look for numbers such as speed, spawn rate and size. Changing one value and replaying is the quickest way to find the right balance. Keep these values grouped at the top of the file so they are easy to find.
Add a reason to replay
Small touches bring players back: a best score saved in the browser, a short streak counter, or a new colour theme unlocked at a milestone. Describe one of these at a time, test it, and keep what makes the game more fun.
Give it a look
Ask for a theme: night sky gradient, glowing stars, a friendly font. You can also generate artwork with the image tools in SiteSim for a title screen or background. If you want to make 3D models for a later project, try SimplexGen.
Handle different screens
Resize the preview to a phone width. Confirm that the play area fits, buttons are large enough to tap and text stays readable. Ask the AI to "keep the game area inside the viewport without scrolling" if anything spills over.
Share and learn from players
Your sim has a link you can send to friends. Watch how they play, then update the game and share the same link again. The gallery shows what other creators have built, which is a lovely source of ideas for your next game.
Export when you are ready
With Pro, deep export packages your project so you can host it anywhere. Small code experiments also fit nicely in WebFiddle.
Start playing with ideas
Open SiteSim, type your two sentence game idea and press go. Your first playable version can be on screen in moments.
