Make a playable release, not just a working file
A game that works on your computer is a strong start. A release also needs clear instructions, predictable controls, an honest description, and a reliable way to open it. Keep the first version small enough that you can test every path.
Test the complete round
Play from the start screen to each ending. Restart immediately after losing, restart during a round, and try input before the round begins. Memory games need testing during mismatch delays. Reaction games need an early tap test. Real-time games need testing after switching to another tab and returning.
- Check that one action produces one result, even if a key is held down.
- Keep the score and game-over message visible on a small screen.
- Ensure restarting clears previous timers and objects.
- Test at least one touch device and the desktop browsers your audience uses.
Make the controls discoverable
List controls next to the game, not only in a separate guide. Give buttons descriptive labels. Use visible keyboard focus, and avoid relying on color alone to communicate a win, a mistake, or a cue. A reaction game can show the word “GO” as well as turning green. Touch controls should have enough space around them to reduce accidental presses.
Canvas games cannot automatically expose every visual detail to assistive technology. Provide text instructions and status messages, and be honest about what the game supports. For a more accessible project, consider a turn-based game with ordinary HTML buttons, such as Three in a Row.
Keep the download understandable
Package only files the player or developer needs. Include a README with the controls, how to open the game, and the settings worth changing. Keep the MIT license with any redistributed template code. If you add art, sound, or fonts, track their separate licenses: the code license does not grant permission to use unrelated assets.
Host the game
These starters use static HTML, CSS, and JavaScript. A static web host can serve them without a database. Upload the game folder, keep the entry file named index.html, and check the deployed URL on a second device. Use HTTPS and verify that all paths resolve after deployment. A link that works on your hard drive can still fail if the server treats uppercase and lowercase filenames differently.
Describe it accurately
Explain the objective, input method, and expected length of a round. Do not promise features that the release does not include. A local two-player game should say it uses one shared device. A score that exists only during the current session should not be described as a leaderboard.
If you plan to monetize
Build a useful destination around the games: original explanations, documented downloads, and clear navigation. Keep advertisements away from active play controls and download buttons. Never encourage players to click ads, and do not turn an ad into a required game action.

Publish a small changelog
Give the version a number and record what changed. Ask a tester to explain the rules back to you after one round. If they need you to guide every step, improve the instructions before adding another feature. A clear first release gives you a stable base for the next one.
