How to Create and Publish Your First Game in 7 Days

Have you ever played a game and found yourself thinking, “I could make this”? Or maybe you have a brilliant idea for a multiplayer challenge, but it stays locked in your head because you don’t know C++ or Python.

For a long time, game development has felt like an exclusive club. Unless you had years of coding experience or a massive budget, making something playable seemed impossible. You might think you need to hire a team of artists or spend months learning complex software just to get a character moving on a screen.

But that reality has changed. With Astrocade, the barrier between “player” and “creator” is thinner than ever. You don’t need a computer science degree. You don’t need to spend six months on a prototype. In fact, if you start today, you can have your very first game published and playable by this time next week.

Here is your step-by-day beginner game design guide to going from zero to launch in just seven days.

Day 1: Play to Learn

Before you build, you must observe. Your first day isn’t about working hard; it’s about playing smart. You are probably already familiar with the AI game development platform, but today, you need to look at it through a different lens.

Instead of playing just to win, play to understand how the game works. Pick three popular games on the platform and dissect them.

Take a look at a hit like Umamusume Dash. On the surface, it’s a high-energy racing game. But look closer at the mechanics. What makes it fun? Is it the speed? Is it the way the camera moves? Is it the simplicity of the goal?

Then, switch gears and look at Among Us Seek & Hide. This game relies on tension and social interaction. Notice how the map is designed. Are there tight corners that make hiding easier? How does the game tell you who is “it”?

Your Mission for Day 1:

• Play three different types of games on a no-coding game creation tool (e.g., a racer, a puzzle game, and a shooter).
• Write down one specific thing you liked about each one.
• Write down one thing you found frustrating.

Pro Tip: Don’t worry about graphics right now. Focus on the “fun factor.” A simple game that is fun to play is always better than a beautiful game that is boring.

Day 2: The One-Sentence Pitch

The number one mistake new game developers make is “scope creep.” This is when you start with a simple idea, like “a game about a cat,” and suddenly you’re trying to build a massive open-world RPG with a complex economy and voice acting.

You have one week. You need to keep it small.

Today is about defining your concept. You need to create a “Core Loop”—the primary thing the player will be doing for 90% of the game. If you can’t describe your game in one sentence, it’s too complicated for your first project.

Examples of strong, simple pitches:

• “A racing game where you play as a runaway tire.”
• “A survival game where the floor turns to lava every 10 seconds.”
• “A capture-the-flag match set on the moon.”

Your Mission for Day 2:

• Brainstorm three ideas.
• Pick the simplest one.
• Write your one-sentence pitch on a sticky note and put it on your monitor. Do not deviate from this sentence!

Day 3: Building the Environment

Now it’s time to open the game creator tools that use AI to build new games. If you’ve never opened the editor before, don’t panic. It’s designed to be intuitive.

Today, you are the architect. You aren’t worrying about rules, scoring, or winning just yet. You are simply building the stage where the action will happen.

Use the drag-and-drop assets to construct your map. If you are making a racing game, lay out the track. If you are making a shooter, build the arena. Focus on the flow of the space. Is there enough room for the player to move? are the platforms reachable?

Don’t spend four hours trying to make a tree look perfect. Use the pre-made assets available in the library. Your goal is to get the “bones” of the level built.

Your Mission for Day 3:

• Open a new project file.
• Lay down the floor and walls of your level.
• Place key landmarks (like the starting area and the goal).
• Run around in the empty level to see if the size feels right.

Day 4: The Mechanics

This is the day that usually scares people. This is where “coding” usually comes in. But remember, the goal is to make a game without coding.

Game development with AI tools allows you to set up logic visually. You are essentially setting up rules. Think of it as “If This, Then That.”

• If the player touches the finish line -> Then show the “You Win” screen.
• If the player falls off the map -> Then respawn them at the start.

Look back at the simplicity of Umamusume Dash. The core mechanic is movement. On Day 4, you need to make sure your player can interact with the world. Set up your win conditions and your loss conditions.

Your Mission for Day 4:

• Set the player spawn point.
• Create the “Goal” or “Win” trigger.
• Test that the game ends when you reach the goal.

Pro Tip: Keep your mechanics consistent. If red objects kill the player in level 1, don’t make red objects safe in level 2. Players learn by doing, so don’t confuse them!

Day 5: The Challenge

You have a map, and you have a rule for winning. Now you need to make winning difficult. A game without a challenge isn’t a game; it’s just a simulation.

Today is about adding obstacles. If you look at Among Us Seek & Hide, the challenge comes from the other players or the environment. For your game, think about what stands between the player and victory.

If it’s a platformer, add gaps that are slightly tricky to jump over. If it’s an action game, drop in some enemy AI or turrets. If it’s a puzzle game, add a locked door that requires a key.

Be careful not to make it impossible. It should be “tough but fair.” The player should feel smart for beating your level, not lucky.

Your Mission for Day 5:

• Add at least three different types of obstacles (e.g., spikes, enemies, moving platforms).
• Place “checkpoints” if the level is long so players don’t lose all their progress.
• Ensure there is a clear path from start to finish.

Day 6: Testing & Polish

You are almost there. Your game is playable, but is it ready for the world? probably not yet. Day 6 is for quality assurance.

Play your game. Then play it again. Then play it three more times. Try to break it. Run into walls, try to jump out of bounds, and see what happens if you press buttons you aren’t supposed to.

You will find bugs. Maybe the player gets stuck in a corner, or the enemy doesn’t see you. This is normal! Use today to tweak those settings.

Once the game plays smoothly, you need to dress it up for the store. A game with a blank thumbnail gets zero clicks. Take a cool screenshot of your level. Write a catchy description using the pitch you wrote on Day 2.

Your Mission for Day 6:

• Play through your game from start to finish at least 5 times without errors.
• Take a screenshot that shows the most exciting part of the game.
• Write a title and a description.

Pro Tip: Ask a friend to play it while you watch. Don’t say anything. If they get confused, that means your game design isn’t clear enough. Fix the confusing parts.

Day 7: Launch!

It’s been a busy week, but you’ve arrived. You have a concept, a built world, working mechanics, obstacles, and a polished final product.

There is only one thing left to do: Publish your first game.

It can be nerve-wracking to put your work out there. You might worry that people won’t like it or that it’s too simple. Push those thoughts aside. Every great game creator started exactly where you are right now. The difference between a dreamer and a developer is hitting that “Publish” button.

Once it’s live, share the link! Drop it in the community Discord. Send it to your friends. Be proud of what you built.

Your Mission for Day 7:

• Click Publish.
• High-five yourself.
• Share your game with the world.

You Are Now a Game Developer

Seven days ago, you were just a player. Today, you are a creator.

You proved that you don’t need years of school or complex code to bring an idea to life. You just needed a plan and the right tools. The game you built this week is just the beginning. Now that you know the workflow, what will you build next week? A multiplayer arena? A story-driven adventure?

The tools are ready when you are.
