A simple, cross-platform 2D game engine with OpenGL and Vulkan renderers.
|
|
Supports Linux and Android platforms.
|
|
This is a personal hobby project. I've published a little game on
|
|
[Google Play](https://play.google.com/store/apps/details?id=com.woom.game)
|
|
based on this engine. Full game code and assets are included in this repository.
|
|

#### Hello World example:

|
Simply shows a rotating "Hello Wolrd!".
