# Customize Your Game

> Tweak every aspect of your game with zero code using Gummy's visual editor.

## Overview

After generating a game, the visual editor lets you fine-tune everything — from how the player feels to how the world looks. No code, no syntax, just sliders and toggles.

***

## Opening the editor

From any game in your profile, tap **Edit**. The editor opens with your game running in preview mode alongside the control panel.

***

## Physics & Gameplay

Control the core feel of your game with physics settings.

| Setting              | What it does                                                |
| -------------------- | ----------------------------------------------------------- |
| **Gravity**          | Higher = faster falling. Lower = floaty, moon-like movement |
| **Jump Height**      | How high the player can jump                                |
| **Player Speed**     | How fast the player moves horizontally                      |
| **Enemy Speed**      | How aggressively enemies move toward the player             |
| **Projectile Speed** | Speed of bullets, fireballs, or other launched objects      |

<Tip>
  Small changes make a big difference. Try gravity at 60% for a platformer that feels smooth and responsive. Try 150% for a punishing, fast-falling challenge mode.
</Tip>

## Difficulty

| Setting              | What it does                          |
| -------------------- | ------------------------------------- |
| **Enemy Health**     | How many hits enemies can take        |
| **Player Health**    | How much damage the player can absorb |
| **Enemy Spawn Rate** | How frequently new enemies appear     |
| **Obstacle Density** | How packed the level is with hazards  |

## Characters & Art

### Swap your player character

Tap the **Character** panel to browse Gummy's asset library. You can:

* Choose from hundreds of pre-built characters
* Filter by style (pixel art, cartoon, realistic, retro, sci-fi...)
* Upload your own sprite (PNG with transparent background)

### Swap enemy characters

Same process as above — tap any enemy in the preview to select and replace it.

### Change the environment

Tap the **Environment** panel to change:

* Background art (sky, dungeon, space, city, forest...)
* Ground/platform tiles
* Color palette
* Lighting style

***

## Level Design

Use the **Level Editor** to adjust the layout of your game world:

* **Drag and drop** platforms, obstacles, enemies, and collectibles
* **Resize** platforms by dragging their edges
* **Add new levels** with the + button at the top
* **Delete** elements by long-pressing and tapping Delete

<Note>
  Level editing is available for platformers, puzzle games, and RPG adventures. Endless runners and shooters use procedural generation — you can tune their parameters but not hand-build their layouts.
</Note>

***

## Sound & Music

* **Background music** — choose from Gummy's built-in soundtrack library or turn music off
* **Sound effects** — swap jump, hit, collect, and death sounds from the SFX library
* **Volume** — control music and SFX volume independently

## Saving your changes

Changes auto-save as you edit. Tap **Preview** at any time to playtest with your current settings. When you're done, tap **Done** to return to your game profile page, then **Publish** to push updates live.
