I never did this before, so be gentle please. :-)

We have the itch.io game page. How do we actually submit it?

On the game jam page there is a submit button I think where the time left in the jam part is

Go to this page: https://itch.io/jam/tgcxcoreblazer

Press: Submit Your Project, that is next to the time countdown.

Under the existing projects choose the game page that have you already uploaded. Also fill in the necessary fields. Hit submit.

Hope that helps!
