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 |
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.
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
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.
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.
