My game actually just got updated yesterday (here's the link https://vinik123.itch.io/bitbrain ) and I'm just keeping my old page.

I may continue mine. But most of the code I made was pretty rushed so I think I'll just start over with the same name and concept.

I'll keep the same page though. Some people keep the old page and create a new one, but I'd just like to have one page for both. Less crowded /on my account page that way.

I'd update the current project that way it shows that it was part of the game jam when people look it up, gives the game a bit of flare to its page in my personal opinion.

I continued mine on a different page because I changed my project a lot.  https://keahunuitechnologies.itch.io/distant-past  I'll check out whatever you decide to do.  If you're looking for an audience I'd recommend colabing with other devs on these community posts.  Devlogs are great too.
