What problem does Jump solve?

Most mobile games either chase hyper-casual trends or deep, complex loops. There’s very little in-between that feels fresh, physically intuitive, and easy to brand.

Jump fills that gap: it’s simple to understand, fun to master, and endlessly extensible. The core mechanic—timed rope jumps—translates well for kids, teens, and adults, and can be skinned for fitness, esports-style competition, or playful character-driven worlds.

Modular Packages

The Jump codebase is organized as a monorepo with independent packages, making it ideal for reuse across other games.

Developer Experience & Setup

Jump is built as a real game project, not a toy demo. The modular packages let you tweak the engine, add levels, or upgrade multiplayer without ripping apart the app.

# Clone the Jump repo
git clone https://github.com/YOUR_ORG/jump_game.git
cd jump_game

# Install dependencies for all packages
flutter pub get

# Run the mobile app
cd apps/jump_mobile
flutter run
          

Firebase configuration is managed via firebase_options.dart per environment. Secrets and keys should live in CI/CD or secure configs, not in the repo.

What you get with Jump

  • A complete, brandable jump rope game ready for polishing and launch.
  • A modular game architecture you can reuse for future arcade or fitness titles.
  • Multiplayer-ready structure with matchmaking and leaderboards.
  • A foundation for tournaments, events, seasonal content, and cosmetics drops.
