How to Make a 2D Game — From Idea to Playable Build in 2026
How to make a 2D game from scratch. Engine selection, art pipeline, basic game loop, and getting to a playable prototype — from a developer who ships 2D games.
By the Choost Games team — we build 2D games in Phaser 3. Granny's Rampage is our current project. This guide comes from what we actually do, not what we read about.
How to Make a 2D Game — From Idea to Playable Build in 2026
Pick Godot or Phaser, make a character that moves, add one enemy, add one way to win. That's your first game. Everything else — art polish, sound design, UI, menus, progression systems — is iteration on top of a working prototype. The single biggest mistake new game developers make is planning a massive game instead of building a tiny working one.
Step 1: Pick Your Engine
You have three realistic options for 2D games in 2026. Each is free and each has tradeoffs.
Godot — best for solo developers making standalone 2D games. GDScript is easy to learn, the 2D engine is purpose-built (not a 3D engine pretending to be 2D), and it exports to PC, mobile, and web. Use Godot if you want to make a game that lives on Steam or itch.io.
Phaser — best for web-first games and browser deployment. JavaScript/TypeScript, runs in any browser, and the ecosystem is mature. We use Phaser for Granny's Rampage because we wanted web-first with Electron wrapping for Steam. Use Phaser if you're comfortable with web development or want your game playable without installation.
Unity — more powerful than you need for most 2D games, but has the largest tutorial ecosystem and asset store. Use Unity if you already know C# or plan to eventually make 3D games.
Don't spend more than one day choosing. The engine matters far less than finishing the game. Pick one, start building, and switch later if you need to.
Step 2: Make Something Move
Before art, before story, before game design documents — make a colored rectangle move on screen with keyboard input. This is your player character. It doesn't need to look like anything. It needs to respond to your input.
In Godot, this is a CharacterBody2D with a simple script. In Phaser, this is a sprite with keyboard input bindings. In Unity, this is a Rigidbody2D with a movement script.
The code is 10-20 lines in any engine. Every tutorial for every engine covers this in the first lesson. Do the tutorial, get the rectangle moving, and you've cleared the hardest barrier in game development: starting.
Step 3: Add Collision and One Enemy
Make a second rectangle. Give it simple behavior — move toward the player, or move in a pattern. Add collision detection so the player knows when they touch the enemy. When they collide, something happens (player loses health, enemy disappears, score increases).
You now have a game. Not a good game, not a finished game, but a functional game loop: move, avoid or engage enemies, something happens on contact. Every game in existence is an elaboration on this core.
Step 4: Add a Win and Lose Condition
The player needs a reason to keep playing and a way to fail. For a prototype, these can be simple. Kill 10 enemies to win. Touch an enemy 3 times and you lose. Survive 60 seconds. Reach the right side of the screen.
With movement, enemies, collision, and win/lose conditions, you have a complete game. Playtest it. Is moving fun? Is the enemy behavior interesting? Is the difficulty fair? These questions matter more at this stage than any art or sound.
Step 5: Replace Rectangles With Art
Now — and only now — make it look like something. Your player rectangle becomes a character sprite. Your enemy rectangle becomes a monster or obstacle. Your background becomes a scene.
For pixel art (the fastest art pipeline for solo devs), see our how to make pixel art guide. Start at 32x32 sprites, use a limited palette, and don't aim for perfection. Placeholder art that communicates "this is the player" and "this is an enemy" is sufficient for months of development.
Tools: Aseprite ($20) for pixel art, Piskel (free, browser-based) for quick sprites, Tiled (free) for tile-based level design.
Step 6: Add Sound
Sound design is the most undervalued part of game development. A silent game feels dead. A game with even basic sound effects feels alive.
Free sound sources: Freesound.org (CC-licensed effects), jsfxr (procedural retro sound generator, browser-based), OpenGameArt (game-specific audio assets).
Music: Start with royalty-free tracks from Incompetech or Free Music Archive. If your game gains traction, commission original music later. Don't let music production block your game's development.
Add three sounds minimum: player action (attack/jump), enemy hit, and game over. These three sounds transform how your game feels.
Step 7: Build, Test, Iterate
Your game is now playable with art and sound. This is where the real work begins — and where most people quit. The prototype-to-finished-game gap is wider than the idea-to-prototype gap.
The iteration loop: playtest → identify the weakest element → fix it → playtest again. Do this 100 times. Each cycle, the game gets slightly better. After 100 cycles, it's a different game than what you started with — and it's actually good.
What Nobody Tells You
Your first game will be bad. This is fine. Ship it anyway. Put it on itch.io. Your second game will be better because you finished your first.
Scope is the enemy. The game in your head has 50 levels, 30 enemy types, a crafting system, and multiplayer. The game you can finish has 5 levels, 4 enemy types, and a score counter. Make the small version first. Expand later if people care.
Programming is the easy part. The hard part is design decisions: is this fun? Is this too hard? Is this too easy? Does this level communicate what the player should do? These questions don't have code solutions.
Nobody will play your game unless you tell them about it. Marketing isn't optional. Post development screenshots on social media. Share your game on itch.io forums. Submit to indie game events. The "if you build it, they will come" philosophy does not work.
