How to Reskin a Unity 2D Game (Step-by-Step Guide)
Nov 07, 2025Introduction
Are you looking to create your own mobile game without building everything from scratch?
Reskinning a Unity 2D game is the easiest and fastest way to launch a brand-new title using an existing source code.
In this guide, you’ll learn exactly how to modify graphics, sounds, and assets in a Unity project to make it completely unique — even if you’ve just purchased the source code from Ready Game Code.
What You’ll Need
Before you start reskinning, make sure you have the following tools and files ready:
- Unity Editor (2021.3 or higher)
- Image editing software: Photoshop, Figma, or GIMP
- New game assets: characters, buttons, background, and UI elements
- Your Unity source code: downloaded from Ready Game Code
- Android SDK & JDK for testing and exporting the APK
Step-by-Step Guide to Reskin a Unity 2D Game
Step 1: Open the Project in Unity
- Extract your purchased source code ZIP.
- Open Unity Hub → Add Project → Select the extracted folder.
- Let Unity import all the assets (it may take a few minutes).
Tip: Always use the same Unity version mentioned in the project’s documentation to avoid compatibility issues.
Step 2: Replace Sprites and Textures
- Navigate to the Assets → Sprites folder.
- Replace existing images (PNG/JPG) with your new ones.
- Keep the same file names and sizes so Unity automatically updates the visuals in the scene.
Pro Tip: Use consistent resolution (like 512x512 or 1024x1024) to keep graphics crisp and avoid stretching.
Step 3: Update the UI and Fonts
- Open your Canvas or UI scene.
- Replace buttons, icons, and logos with your new art.
- Update text fonts using TextMeshPro (recommended for better clarity).
Add your own brand logo or splash image for a professional look.
Step 4: Change Game Name, Package ID, and App Icon
- Go to File → Build Settings → Player Settings.
- Under “Other Settings,” update the Package ID.
- Add your new app icon under the “Icon” section.
- Change the Product Name to your game’s title.
This makes your game uniquely identifiable on the Play Store.
Step 5: Replace Audio and Sounds
- Go to Assets → Audio and import your new background music or sound effects.
- Update audio references in the Inspector if needed.
Step 6: Test the Game
- Click the ▶️ Play button inside Unity to preview gameplay.
- Check for missing textures, misplaced sprites, or UI overlap.
- Make sure all buttons and transitions work smoothly.
Test on different screen sizes (480p, 720p, 1080p) to ensure responsive layouts.
Step 7: Build and Export Your Game
- Go to File → Build Settings → Android → Build.
- Generate an APK or AAB file for testing.
- Install it on your device and play it thoroughly before publishing.
If you plan to upload to Play Store, sign the build with your keystore.
Common Mistakes to Avoid
- Changing asset file names (breaks sprite references)
- Ignoring different screen resolutions
- Forgetting to change splash screen or app icon
- Not testing ads or in-app purchases before release
Final Thoughts
Reskinning Unity games is one of the smartest ways to enter the mobile gaming industry — fast, affordable, and beginner-friendly.
Once you replace your visuals, sounds, and branding, you can publish your unique version on Google Play or App Store and start earning from ads or in-app purchases.
