Quick start: the website
From a blank account to a playable game you have tuned yourself. Everything happens in the browser — there is nothing to install and no API key to configure.
Before you start
You need an email address and a browser. That is the whole list. Every account starts on the Free plan, which comes with free credits every 30 days — enough to build a small game with real art and sound.
Credits pay for generation, not for chatting. Writing code, editing, saving, validating and playtesting are all free. Credits are spent when the platform runs a GPU or an external provider on your behalf — an image, a sound, a music track, a 3D model. See Plans, credits, teams for the full table.
1. Create an account
-
Open the account page
Go to gamentic.net/account and choose No account? Create one.
-
Sign up and verify
Enter an email and a password of at least 8 characters. Your free credits arrive once your email is verified.
-
Check your balance
The account page shows your credit balance, your plan, your game slots and your recent spending. You can come back to it at any time from the avatar in the top right.
Sign-up may be gated by an invite code during the public beta. If the form asks for one and you do not have it, that is the gate — not an error in what you typed.
2. Describe the game you want
Open Make Game. There is a single box: say what you want in one sentence. Genre, art style and the one thing that makes it fun are the three details worth including.
A chicken crossing a busy road. Bright cartoon style, cars get faster
the further you go, with a score and a high score.Two controls next to the box are worth knowing about before you press Start:
| Control | What it does |
|---|---|
| Use a template | Starts from a gameplay blueprint reverse-engineered from a real shipped game — match-3, bubble shooter, Pac-Man, Bomberman, Crossy Road, parking puzzles, roguelike battlers and more. The mechanics and the tuning numbers come from something that is known to be fun, and the art and theme are still yours. |
| Owner | Whether the new game lands in your personal library or a team's shared library. This also decides which wallet pays. You cannot move a game between libraries afterwards, so pick it now if you are working with a team. |
3. Answer the questionnaire
Rather than interrogating you line by line in chat, the agent opens a short form tailored to the genre it detected — a racing game asks about drift and lap counts, a story game asks about characters and endings. Submit it and the agent picks up your answers immediately and starts building.
Fill the form in properly. It is the cheapest step in the whole process and it is the difference between the game you pictured and a generic one. If you would rather skip it, say so in chat and the agent will proceed on your one-line description.
4. Watch it build
The agent works through a visible checklist. Along the way it will typically:
- show you concept art for the main characters and wait for you to pick one, so the game is designed around art you approved rather than art you were handed;
- write the game as a shell plus one file per character, scene and system, so later changes touch one small file instead of the entire game;
- generate sprites, backgrounds, sound effects and music, which appear in the preview as they land;
- test the game in a real headless browser before telling you it is done, and fix what the test reports.
When the build finishes you are taken straight into the Editor with the game running.
You can talk to the agent mid-run. Messages reach it immediately — you do not have to wait for the current step to finish before saying “make the cars slower” or “that character should be a fox”.
5. Tune it yourself
This is the part that makes Gamentic different from a chat window that emits code. The panel on the right of the Editor is a live Inspector built from the values the AI marked as tunable.
-
Drag a slider
Jump height, gravity, enemy speed, spawn rate, colours. The running game picks the new value up on the very next frame. Nothing reloads and no credits are spent.
-
Use the controls around it
Space pauses. Restart replays from the start with your current values. Reset throws your changes away. Ctrl+Z and Ctrl+Y undo and redo — a whole slider drag counts as one step.
-
Save when it feels right
Ctrl+S, or the Save button. This bakes your values into the game's source as the new defaults, so they survive a reload and are what other players get.
Tune before you ask the AI. “Make it a bit faster” is the single most common request in AI game-making, and here it is a slider you drag in two seconds rather than a rebuild you pay for and wait on.
6. Share it
From the Editor toolbar:
| Action | Result |
|---|---|
| Play | Opens the game on its own page — the link works for anyone you send it to, subject to the visibility you set. |
| Share | Sets visibility, invites specific people by email as viewers or co-editors, and turns remixing on or off. |
| Publish | Submits the game to the public Explore gallery. It goes into a moderation queue and shows an awaiting review state until approved. Publishing also runs a real browser interaction test, which takes about 15 seconds. |
| Export | Downloads the game so it runs offline, anywhere, with no dependency on Gamentic. |
| History | Every version is kept. Roll back to any earlier one. |
What this cost
A small first game — one screen, one mechanic, roughly 25 images, a few sound effects and one music track. The Free plan's allowance goes toward a game like that; the credits guide breaks down the per-item prices.
On the website, the agent's own thinking is billed in credits too, because Gamentic is running the model for you. Roughly half of a website build's credits go to the AI's reasoning and half to art and audio. If you connect your own AI over MCP instead, you pay your own provider for the model and every Gamentic credit goes to generation.
