FOSS gamedev and creative worlds

I want to upload my Minetest game Clonecraft to GitHub, but when I try to upload it, it won't let me, saying there are too many files. Worse, when I try adding the game piece by piece, I keep adding the wrong files to the wrong directories.
In short, is there a simple, straightforward way to upload a Minetest game to GitHub? How does everyone else do it?

I used to do it using Chromium browser,
but I always had a hard time of it.

I found this on github and love it.

Thanks so much for the timely response.
Does this program let you upload to repos in bulk?

What do you mean in bulk?
More than one repo at a time?
IDK.

My first repo I used it on was a texture pack.
It wasn't a large filesize
but it has almost 1000 textures in it
and I had no problems with it.

Multiple files.

yeah that's kinda what the second part of my post addresses, Mineyoshi.

You could make separate repositories for the mods and use submodules.

That would be too complicated; I want everyone to be able to download my game the same way they download everyone else's games (LOTT, Overcraft, etc.). Everyone can do it except for me :/
I'll try Git for Windows and see if it works.

Github is a version control host, you upload changes not files. These changes may create or update files

Git is a very useful skill once you've learned it

You should try and make each commit a single change, like:

Add feature X
Fix bug that caused Y
