I appreciate your idea and admit that I too had a similar attitude. Not that I was expecting tons of attention or anything- I mean these are my failed projects after all. It is fun to dust them off and display them, but I agree that if we wanna get some love, we should be more than willing to give a little too.
I will try to play 40-60% of them and add feedback as well. I think that is a fair sentiment. I do apologize for posting so many too! I have a lot of unfinished, shelved projects, and I never saw the right opportunity to share those until this game jam so I took advantage.
