Build Games using Jetpack Compose
Jetpack Compose Is Only for UI? Not Exactly—You Can Make 2D Games
For a long time, many developers believed that Jetpack Compose is only for UI, and that making games with it is impossible or a bad idea.
That statement is partly correct—but also misunderstood.
How to build Android games using Jetpack Compose
Jetpack Compose is not a game engine like Unity, Godot, or Unreal.
But that does not mean you cannot build games with it.
In fact, you can build simple and fun 2D games using Jetpack Compose, especially arcade-style games like:
- Bubble shooter
- Archery or bow shooting games
- Endless runner
- Simple platformer
- Casual arcade shooters
- Snake Feeder
- 15 Puzzle Game
- Thetris Game
Let’s explain the reality clearly.
✅ What Jetpack Compose Really Is
Jetpack Compose is a latest UI framework by Google for Android.
It is designed for:
- Apps
- Animations
- Interactive UI
- Custom drawing
- Gesture handling
- But Compose also provides:
- Canvas drawing
- Coroutines for game loops
- Animation APIs
- Pointer input (touch, drag, gestures)
- State management
👉 These are exactly what simple 2D games need.
🎮 Yes, You Can Make 2D Games in Jetpack Compose
You can create:
✔ Game Objects
- Player character
- Enemies or bubbles
- Bullets
- Obstacles
✔ Game Mechanics
- Drag left/right movement
- Shooting bullets
- Falling objects
- Collision detection
- Score system
- Levels and difficulty scaling
✔ Visual Effects
- Glow effects
- Sprite animation (running frames)
- Explosion animation
- Scaling and rotation
- Particle-like effects
All with Compose Canvas and animations.
⚠️ But Jetpack Compose Is NOT for Complex Games
This is important.
Compose is NOT suitable for:
- ❌ High-FPS 3D games
- ❌ Heavy physics simulations
- ❌ Multiplayer FPS
- ❌ Large open-world games
- ❌ GPU-intensive real-time rendering
Why?
Because Compose is built on Android UI toolkit, not a game rendering engine.
It runs on the main UI thread, not a dedicated game loop engine.
When Jetpack Compose Is a Good Choice for Games
Use Compose for games when:
✅ The game is 2D
✅ Graphics are simple sprites or shapes
✅ FPS requirement is moderate (30–60 FPS)
✅ You want Android-native development
✅ You prefer Kotlin and Compose ecosystem
✅ Game is casual or arcade style
Many indie developers use Compose for fun experimental games and learning projects.
⚔️ Jetpack Compose vs Real Game Engines
| Feature | Jetpack Compose | Unity / Godot |
|---|---|---|
| UI | Excellent | Good |
| 2D Simple Games | Good | Excellent |
| 3D Games | ❌ No | ✅ Yes |
| Physics Engine | ❌ No | ✅ Built-in |
| Asset Pipeline | ❌ Manual | ✅ Built-in |
| Performance | Medium | High |
| Cross-platform | Android only | Android, iOS, PC, Web |
Why Developers Still Build Games in Compose
Because:
- No need for heavy engines
- Full control in Kotlin
- Easy integration with Android features
- Great for learning game programming
- Lightweight APK
- Perfect for educational or casual games
Some developers even publish Compose games on Google Play.
