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.
SettingWhat it does
GravityHigher = faster falling. Lower = floaty, moon-like movement
Jump HeightHow high the player can jump
Player SpeedHow fast the player moves horizontally
Enemy SpeedHow aggressively enemies move toward the player
Projectile SpeedSpeed 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

SettingWhat it does
Enemy HealthHow many hits enemies can take
Player HealthHow much damage the player can absorb
Enemy Spawn RateHow frequently new enemies appear
Obstacle DensityHow 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.
