Everything you need, start to publish.
Short, practical answers. If something isn't here yet, ask the AI assistant inside the builder — it knows the engine.
1. Start with one clear sentence
The builder works best when your first message names the kind of game and one thing that makes it yours.
- Good: "A top-down shooter with homing missiles and a boss every five levels."
- Less good: "Make a fun game."
- You can change anything later — the first sentence only picks a starting point.
2. Ask for changes in plain English
Every message can adjust mechanics, difficulty, enemy behaviour, or win conditions.
- "Enemies should zigzag and get faster each level."
- "Give the player three lives and a shield power-up."
- "Win the level by collecting all the keys instead of shooting everything."
3. Generate art that matches
Ask for the art you need and it is generated in a consistent style, sized for the engine and cut out with a transparent edge.
- Players, enemies and bosses face right — the engine rotates them as they move.
- Ask for a whole set at once: "player ship, three enemy types, and a power-up icon."
- Prefer your own art? Upload it and assign it in the editor tabs.
4. Understand the background layers
Backgrounds are stacked by depth, and each layer does a different job.
- Layer 3 — the ground. A full, opaque texture.
- Layer 2 — surface detail on top of the ground, mostly transparent.
- Your game plays above those two layers.
- Layer 1 — overhead detail such as clouds, drawn above the player.
- Layer 4 — an optional collision mask: anything painted is solid, transparent is open space.
5. Play as you go
The game runs beside the chat, so you can test after every change.
- Hit Refresh in the top bar to reload the latest version.
- The progress checklist shows what is still missing before the game feels finished.
6. Publish, share, and embed
Publishing gives your game its own web address that anyone can open.
- Publish from the top bar or the checklist; add a short note about what changed.
- Copy the link and share it — it works on phones and laptops, no install.
- Embed it in a page or blog post with the embed link.
- High scores are built in, so players can compete on your game.
7. Credits, in one line
Creating, playing, sharing and remixing are free. AI messages and AI art use credits.
- New accounts get 30 credits plus three free art generations.
- Credits never expire. Memberships include monthly credits and unlock unlimited games.
