How to Make a Platformer Game with AI in Minutes

Make your own platformer game with AI. No coding required. Step-by-step guide to creating a Mario-style platformer in Summer Engine, from first prompt to playable game.

Platformers are the most intuitive game genre. Run, jump, avoid obstacles, reach the goal. Everyone has played one. Everyone has imagined making one.

Making a platformer in a traditional engine (Unity, Godot, Unreal) takes days of work -- setting up tilemaps, programming player movement, configuring physics, designing levels. In Summer Engine, you describe the platformer you want and play it in minutes.

Here is how.

What You Will Build

A complete 2D platformer with:

  • A player character that runs, jumps, and double-jumps
  • Platforms with different behaviors (static, moving, crumbling)
  • Collectible items (coins, gems, power-ups)
  • Enemies with patrol behavior
  • Multiple levels with increasing difficulty
  • A start screen and game over screen
  • Sound effects and background music
  • Exportable to Steam, desktop, or web

This is not a browser demo. It is a real game project in the Godot engine that you own and can customize, extend, and ship.

Step 1: Start with a Template

Open Summer Engine and start a new project. When asked what you want to build, choose the Platformer category. You will see templates like:

  • 2D Platformer -- classic side-scrolling Mario-style
  • 3D Platformer -- third-person camera, 3D environments
  • Precision Platformer -- Celeste-style tight controls and difficult jumps
  • Puzzle Platformer -- platforming combined with puzzle mechanics
  • Metroidvania -- interconnected world with ability gating
  • Endless Runner -- auto-running with obstacle dodging
  • Co-op Platformer -- two-player cooperative platforming

Pick 2D Platformer if you want the classic experience.

Step 2: Describe Your Game

The AI does not just generate a generic platformer. It builds what you describe. Here are example prompts at different levels of specificity:

Simple (great starting point):

Make a 2D platformer with a knight character. The knight can run, jump, and attack enemies with a sword. Include coins to collect and 3 levels that get harder.

More detailed:

Create a side-scrolling platformer set in a haunted forest. The player is a small fox that can run, wall-jump, and dash. Enemies are ghosts that float in patrol patterns. Collectibles are glowing orbs. The visual style should be dark and moody with pixel art. Include a double-jump ability that unlocks after level 2.

Very specific:

Build a precision platformer with tight controls. The player character should have: run speed 200, jump height 400, dash length 150 with a 0.5 second cooldown. Gravity scale 2.5 for fast falls. Include coyote time (0.1 seconds of grace period after leaving a platform). Levels should use a tilemap with ground tiles, spike tiles (instant death), and bounce pads. No enemies -- pure platforming challenge. Include a death counter and speedrun timer.

The AI takes your description and creates:

  • Scene tree with player, camera, tilemap, and level nodes
  • Player controller script with the movement you described
  • Enemy nodes with patrol behavior (if requested)
  • Collectible items with pickup logic
  • Level transitions
  • UI for score, health, and menus

Step 3: Play and Iterate

After the AI builds your game, you can play it immediately in the editor. Then iterate through conversation:

"Make the jump feel floatier -- reduce gravity and increase air control"

"Add a wall-slide mechanic so the player slows down when touching walls"

"The second level is too easy. Add more gaps and two more enemies"

"Change the background to a sunset gradient. Add parallax scrolling"

"Add a checkpoint system so the player respawns at the last checkpoint instead of the start"

Each request modifies the actual game project. The AI edits scripts, adjusts physics values, adds nodes, and reconfigures scenes. You are not starting over each time -- you are building on what exists.

Step 4: Make It Yours

At any point, you can switch from AI conversation to the Godot editor. Everything the AI built is standard Godot -- scenes, scripts, resources. You can:

  • Edit levels visually by painting tiles in the tilemap editor
  • Tweak physics by adjusting export variables in the inspector
  • Add custom art by importing your own sprites and tilesets
  • Write scripts in GDScript if you want custom behavior the AI cannot express
  • Add animations using the built-in animation editor

This is the difference between an AI game maker and an AI game engine. The game maker gives you a result. The engine gives you a project.

Step 5: Export and Ship

When your platformer is ready:

Export to desktop (Steam-ready):

  • File > Export > Windows / macOS / Linux
  • Upload to Steam, itch.io, or distribute directly

Export to web:

  • File > Export > HTML5
  • Host on your own site or share a link

Export to mobile:

  • File > Export > Android / iOS
  • Publish to Play Store or App Store

The export process is the same as any Godot game. Because Summer Engine IS Godot, with AI built in.

What Makes This Different from Rosebud, Star, or SEELE

In Rosebud or Star, you type "make a platformer" and get a browser game. It is playable. It is fun for 30 seconds. But:

  • You cannot edit the tilemap
  • You cannot tweak the jump physics
  • You cannot add wall-jumping or dashing without regenerating the whole game
  • You cannot export it to Steam
  • You cannot bring in custom pixel art
  • You cannot build 10 levels with increasing difficulty

In Summer Engine, you get a real project. The same kind of project a professional indie developer would build in Godot -- but you got there through conversation instead of months of coding.

Platformer Ideas to Try

Not sure what to build? Try one of these:

"Make a game like Celeste"

Create a precision platformer with tight controls, a dash mechanic, and difficult-but-fair level design. Pixel art style. Include a death counter. The player should feel fast and responsive.

"Make a game like Hollow Knight"

Build a 2D metroidvania with a knight character. Interconnected rooms, ability gating (unlock wall jump to access new areas), melee combat, and boss fights. Dark, atmospheric art style.

"Make a game like Super Meat Boy"

Create an extremely difficult precision platformer. Small levels, instant death from any hazard, instant respawn. Include saw blades, spikes, moving platforms, and a timer. The character should be very fast and responsive.

"Make a game like Mario"

Build a classic side-scrolling platformer with a character that runs, jumps, and stomps on enemies. Include coins, question blocks with power-ups, pipes, and a flagpole at the end of each level. Bright, colorful art style.

"Make an endless runner"

Create a side-scrolling endless runner where the player automatically moves right. They can jump and double-jump to avoid obstacles. The speed increases over time. Include a high score system and procedurally generated obstacles.

Get Started

Summer Engine is free to download. You do not need to know how to code. Pick a platformer template, describe what you want, and start playing your game in minutes.

Download Summer Engine | Platformer Templates

Summer Engine is the first AI-native game engine. It lets you create 2D and 3D games through natural conversation. Unlike browser-based AI game makers, Summer Engine produces real games you can export to Steam, desktop, and mobile. With 70+ game templates, built-in asset creation, and a professional editor, it bridges the gap between AI convenience and professional game development.

Frequently Asked Questions

Can I make a platformer without coding? Yes. Summer Engine lets you create complete platformer games through AI conversation -- no coding required. You describe what you want, and the engine builds it.

How long does it take to make a platformer with AI? You can have a playable platformer in minutes. A polished game with multiple levels, custom art, and refined mechanics takes hours instead of the weeks it would take in a traditional engine.

Can I publish my AI-made platformer on Steam? Yes. Summer Engine is built on Godot, which supports full Steam export. Your game is a real Godot project -- not a browser demo.

Is this the same as making a game in Godot? Yes, but faster. Summer Engine is a fork of Godot with AI built in. Everything the AI creates is standard Godot scenes and scripts. You can edit them manually at any time.

What if I want to add features the AI cannot build? You can always switch to the Godot editor and write GDScript manually. The AI and manual editing work together -- use AI for speed, switch to the editor for precision.

Can I make a 3D platformer? Yes. Summer Engine supports both 2D and 3D game creation. Choose the 3D Platformer template to start with a third-person camera and 3D environments.
