Thank you for your questions!
1) There is not but I could see the benefit of that. I run a Discord server for my channel so I could have a category for this but maybe it should be a new server just for this. Either way, that's a good idea.
2) I set the hashtag #2DHorrorGameJam but I'm wondering if I should change it. It started as #Manas2DHorrorGameJam but the "Manas" bothered me since it can be read weird without the apostrophe in there. 😅
Checking now, I'm not seeing any results for #2DHorrorGameJam so maybe we are good to go ahead with that. Open to suggestions!
