Nutshell¶
Nutshell is a lightweight open source game engine.
It is standalone and portable: you don't have to install any other programming software to build or run your games with it!
Ready? Set? Go nuts! 
What is Nutshell?¶
A game engine¶
It is a game engine: It runs your game.
Or any game someone made to be used with it, for that matter.
Nutshell is not limited to games however, any kind of project can be built with its simple framework.
However, it is not (yet!) a game editor, there is no shiny user interface to build your game... you will need to use at least a text editor to write your game's code.
In a nutshell...¶
Nutshell enables you to easily :
- Read keyboard / mouse / gamepad inputs
- Draw primitives
- Draw Images
- Draw Text
- Play Music / Sounds
- and much more!
Multiplatform¶
Nutshell games work on:
Built on the shoulders of giants¶
It leverages the power of the Squirrel programming language and the flexibility of the SDL to provide a simple game programming framework.
It is made with the Go programming language and use PureGo to wrap the Squirrel library, and go-sdl3 to wrap the SDL 3 library.
