I hope you will keep working on this, because it is a very interesting idea for gameplay! As for additional content I would love to see birdLE users with difficulty varieties, some of them easy, with traits right there in their descriptions, some harder where you have to deduce what they are like from maybe latest birdLE's they liked/shared or some other data? Maybe they bought something recently? Maybe they signed up for some newsletter? That would definitely spice up the game :) Good luck with the jam!
