No this is not really open source and will private this repo soon.
if you try to clone this there's 100% will not work since I didn't include the important file which is the "Engine.cs"
[update 1/10/2023]
Most of the files are now available because I'll be no longer working on this messy project.
if you try using this for your project or other things I'll be happy and thankful if you mention me on your projects :)
