The code is mostly in the https://github.com/GreenteaOS/Tofita and https://github.com/GreenteaOS/Caramel

People check the https://github.com/GreenteaOS/Greentea which currently mostly contains binary assets. This repo will have user-space apps. Currently sample apps are taken from ReactOS project.

Greentea OS is built from scratch in a custom programming language Hexa with custom kernel design (called Tofita Engine)

This is amazing. Is the author of the OS also the author of the language? The language looks pretty high-level; why was it chosen for the OS implementation? What architecture does the kernel have (monolythic, micro, etc.)?

An operating system with great potential. I really hope that the development will not drag on for decades.
