+# 简介
+
+合成大瓜是使用[Flutter](https://flutter.dev/)+[Flame](https://flame-engine.org/)+[Forge2D](https://github.com/flame-engine/forge2d)开发的一个开源小游戏。
+
+我在[微伞小游戏](http://www.wesane.com/)开发的[《合成大西瓜》](http://www.wesane.com/game/654/)的基础上将其移植到 Flutter 平台，并添加了以下新特性：
+
+- 支持自定义背景图
+- 支持重力感应操控
+- 支持修改图片素材
+- 支持反向合成小瓜
+- 支持只生成小/大瓜
+- 内置多套游戏主题（水果/表情/校徽）
