Space Shooter

A retro-style arcade space shooting game built with Flutter and Flame Engine.

Built with AI: This game was developed using self-evolving-agent's /evolve skill - an autonomous AI agent that learns and iterates until goals are achieved.

How This Game Was Built

This project demonstrates AI-assisted game development using the self-evolving-agent workflow:

Step 1: Create Domain Skill

First, a Flame Engine skill was created based on the Flame Engine documentation. This skill encapsulates:

• Flame architecture patterns (FlameGame, Components, World/Camera)
• Input handling (keyboard, touch, joystick)
• Collision detection system
• Sprite animation patterns
• Audio integration
• Common game patterns (object pooling, spawners, parallax)

Step 2: Evolve the Game

With the Flame skill in place, the /evolve command was used to iteratively build the game:

/evolve 建立一個太空射擊遊戲
/evolve 加入武器升級和道具掉落系統
/evolve 加入多種敵人類型和 Boss
/evolve 部署到 GitHub Pages

The self-evolving-agent autonomously:

• Searched memory for relevant patterns
• Applied Flame Engine best practices from the skill
• Implemented features with proper architecture
• Tested and fixed issues iteratively
• Deployed the final product

Development Time: ~40 minutes (initial) + ~20 minutes (enhancements)

Initial build (~40 minutes):

• Game architecture setup
• Player with 4-level weapon system
• 6 types of power-ups with drop system
• 5 enemy types with unique behaviors
• Boss battle system
• Wave progression
• HUD with lives display
• GitHub Pages deployment

Enhancement update (~20 minutes):

• 5 weapon types with unique properties
• 3 new enemy types with multi-directional spawning
• Enhanced Boss with 3-phase difficulty
• 12 power-up types
• Formation bonus system

Bug fixes (2026-01-13):

• Fixed Bomb power-up not clearing enemies (recursive search for nested components)
• Added visual confirmation flash effect when Bomb triggers
