Hi, hello, happy new year

I'm really, really, really new on game jams, and I feel lost.

The game needs to be in english? (That's not my native language).

"Create a new repository to store the source code and any assets you’re able to share for your entry..." I have to put ALL the source code?

Andd, I can use Ren'Py? Have any problem in make a visual novel?

I'm sorry all that's questions, and thank you.
