How to make a game with AI

Start from a sentence

Describe what the player does, what they are trying to achieve, and how the game responds. For example: 'A cozy fishing game on a haunted lake. Catch three ghost fish, return them to the dock, and show a win message.' Use this as a starting prompt, then ask the AI to build the first playable loop.

Build your world or map with AI

Tell Gessa where the player starts, which places they can reach and what draws them through the world. For the fishing idea, begin with a dock, a lake and a path back to the goal. Work with the AI on the layout and game interactions, then explore the result as a player.

Give the map a recognizable landmark and check that the route to the goal is clear. Add detail around the working layout: scenery, surface textures, lighting and background sound. You can keep changing the world as you decide how the game should feel.

Help me build a small haunted-lake map for a fishing game. Put the starting point on a wooden dock, a lantern beside the path and a clear place to return with the fish. Start with the layout and movement so I can explore it before we add detail.

Generate the pieces

Generate the assets your game needs: a model such as a brass lantern, a seamless mossy stone texture, and an audio effect for catching a fish. Add behavior with a concrete request such as 'when the player picks up the lantern, light the nearby torches.' Keep the assets and rules together in the project as you refine them.

Refine and play

Run the game and check movement, interactions, progress and the win condition. Ask for one specific change at a time, then test again. Use AI and visual tools to edit the project, visual scripting to shape behavior and generated code views to inspect it. Invite a friend to collaborate, and test shared rules with multiple players when making a multiplayer game.

Make the first moments clear for a new player

Show the goal where a player will see it and explain the controls they need to begin. Ask a friend to try the game without coaching them. Watch whether they know where to go, what they can interact with and when they have completed the goal.

For a game you want people to play on a phone, test on the actual device and browser before sharing it as a mobile game. Check touch controls, readable text, sound and loading as well as whether the scene appears.

Play in the browser

Publish the game and share its public play page with friends. Open that page separately from the editor and check loading, controls and the complete game loop. Try the browsers and devices you expect players to use, then keep improving the game from their feedback.
