Open sourcing the engine of Heatchain

Hi,

A year after the release of heatchain, I publish the source code of the engine on github: https://github.com/hyultis/Hyultis_Game_Engine

Basically, the engine is based on multithreading and vulkan 1.1 (using vulkano. vulkan 1.1 is a limitation due to the android version, vulkan 1.3 is still quite poorly supported on android).

I invite you to read the README if you want to know more.

Have a nice day
