This guide takes you from a blank dashboard to a published game.

​
Step 1: Describe your game

From your Dashboard, type your game idea into the prompt box. Detail pays off — a strong first prompt covers:
  • Genre & perspective — “top-down dungeon crawler”, “side-scrolling platformer”
  • Art style — “dark pixel art with torchlight”, “vibrant low-poly 3D”
  • Core mechanics — “sword combat, collect gold, find the exit on each floor”
  • Win/lose conditions — “lose when health hits zero”
You can also attach reference images for the art style and pick a model (Muranyi 3.5 is the balanced default). See Prompting for what makes prompts work.

​
Step 2: Review the plan

New games start in plan mode by default: before building, the AI lays out what it intends to make — mechanics, scenes, art direction, scope.
  • Happy with it? Hit Approve & Build.
  • Want changes? Type modifications and approve with changes — the build follows your amended plan.

​
Step 3: Watch the build

The AI agent now builds your game — writing code, creating scenes, generating all assets (images, 3d models, audio & more), then testing. Builds can take tens-of-minutes, because the agent is doing real engineering work (see How Tesana works). You can watch its progress live in the chat panel. If the AI needs a decision from you mid-build, it pauses and asks you. Answer and the AI continues.

​
Step 4: Play and iterate

When the build lands, your game is playable immediately in the Studio’s preview pane. Play it, then keep going with follow-up prompts:
  • “Make the player jump 20% higher”
  • “Add background music and a coin-collect sound”
  • “The enemies clip through walls on level 2 — fix that”
One focused change per prompt gets the best (and cheapest) results. For bugs, describe what you did, what you expected, and what happened instead — and attach a screenshot from the preview. See Debugging your game.

​
Step 5: Publish

When it’s ready to share, publish it:
  1. Open your game’s settings (gear icon in the Studio).
  2. Set up the store page — poster, screenshots, tagline, description (Storefront).
  3. Flip visibility to Published (Publishing your game).
Your game gets a public play link and a place in the marketplace. Paid plans can also export standalone builds and the full source code.
