Vibe game makers: choose a first project

Choose a workflow for your first game

Our editorial first pick for an editable project is Summer Engine. Its product overview describes 2D and 3D creation with the Summer agent or your own, and an editor for scenes and code. Summer owns this publication; this recommendation reflects our preference for continued editing.

If sharing a browser link is the first priority, investigate Rosebud, which describes prompt-based browser game creation. If you would rather make visual rules yourself, Construct’s manual explains its events and actions. These are different workflows; check current plans and output options before committing.

Three small ideas, ordered by scope

1. Collect and exit: move a character, collect three items and reach a door. This tests movement, collision and a win state.
2. One-screen dodger: avoid one moving obstacle and restart on contact. Add difficulty only after the loop works.
3. Short branching story: offer two choices and two endings. This tests text, navigation and state without requiring a large world.

These are suggested projects, not completed tests or a ranking of finished games. Choose the one whose interaction you can describe in one sentence.

From prompt to playable loop

Write the objective, controls and win or loss condition. Ask for the smallest version, then play from start to finish. Change one rule, such as the number of objects needed to win, and confirm the display and win condition still agree. Save a copy before larger changes.

Find the scene or rule behind the interaction. If you cannot find it, ask the agent to explain it and inspect its answer in the editor. Export a build for your intended device and ask a friend to try it without instructions. A generated preview is not proof that an exported build works.

What will it cost?

Check the current Summer pricing page for editor, AI usage and plan limits. A separate agent may have its own charges. For any tool, check whether saving, commercial use, private projects and the export you need require a paid plan. Set a spending limit before starting.

Common questions

Do I need to know how to code?

You can begin with an idea and a prompt, but you still need to make decisions and test the result. Learning enough to inspect a rule helps you fix the next change.

When is the project done?

Set a small finish line: another person can start, understand the goal, finish or lose, and restart. Treat extra levels as a later project.

Compare the workflow, not the slogan

Summer Engine: choose it when you want an agent to help build a game while you keep an editor for later changes. The pricing page lists a free app with manual editing and export, a limited free AI allowance and a free MCP connection. Check whether the allowance and privacy level fit your project. An external agent can have separate costs. An agent’s proposed change still needs your review and a playtest.

Rosebud: consider it when making and sharing a browser game through prompts is the main goal. Its pricing page lists plan-dependent privacy, commercial rights, code download and Windows export. It also describes credits for AI tasks, with usage depending on the model and task. Check the plan covering all of your needs, rather than assuming that a free playable preview includes commercial use or downloadable code.

Construct: consider it if you want to assemble 2D behavior through events, conditions and actions. Its manual is a useful way to see how that workflow is organized. This is a visual-rules alternative, not a claim that Construct offers the same agent integration. Check its current license and publishing requirements before selecting it.

For a fair comparison, use the same brief and the same device. Record where the project is saved, what you can edit yourself, the limits of the plan you used and how you get a build to another person. Our ordering is editorial, based on a preference for editable projects; it is not a comparative benchmark.

A worked first-project brief

Make a single-screen game. Move with the arrow keys, collect three stars, and open an exit. Touching a moving obstacle restarts the level. Show the number collected and a message when the player wins.

Before adding art or sound, test the three state changes: collecting a star increases the count once; the obstacle resets the level; and the exit works only after the third star. If any fails, describe the action and actual result precisely: “I collected the same star twice after restarting; the counter showed four.” Give the agent one defect at a time and replay the whole loop after each fix.

Next, change the requirement from three stars to five. Look for all affected places: the counter, the exit condition and the instructions. This reveals whether the game is easy to maintain after its first draft. If the change breaks a different mechanic, restore a saved version and ask for a smaller change. Keep a note of what you changed and why.

Finally, create the intended build and try it outside the editor. Test the controls, restart and win condition again. Send the build or link to a willing tester, ask them to describe the goal, and watch where they get stuck. Do not call the project finished solely because the editor preview opens.

Choose scope before style

A first project should fit on one screen or contain one short sequence. A racing idea can become “one car avoids three barriers”; a role-playing idea can become “talk to one character and choose one of two replies.” The small version lets you learn movement, input, state and feedback without needing an inventory, online accounts or a large map.

Write down what is outside the first version. Multiplayer, procedural worlds and storefront publishing each introduce separate decisions. Add them only after the basic loop is understandable and repeatable. If you use generated art or third-party assets, check their applicable terms and retain a record of their source before sharing the game.

What should I ask an agent when the result is confusing?

Ask it to identify the relevant scene or rule, describe the expected behavior and propose the smallest fix. Inspect the change and compare the result with the original requirement. An explanation can be wrong, so use play behavior and the editable project as your evidence.

Can I switch tools later?

Sometimes assets or code can move, but an editable project is not necessarily portable between engines. Before investing in a long project, check the exact export format, asset licenses and what you would need to rebuild elsewhere.
