I'm up for any of my games to be streamed. In fact, I don't think I know any creators who wouldn't be thrilled. My only request would be to make sure you tell viewers who made the game and where to find it. Also, if you need to know how to pronounce my name, it's loo-see-EH-lah. Feel free to message me on Twitter at LuciellaES if you'd like a complimentary copy of A Wretched Luncheon With Your Best Friend Who Sucks at Cooking: https://luciellaes.itch.io/wretched-luncheon. Should take around 30-45 minutes, maybe a little longer depending on how you approach it.
In terms of images, this is the one I've used for my game background (it's licensed under CC0) https://pixabay.com/photos/aurora-polar-lights-northen-lights-1197753/
