Very interesting! I didn't quite understand why I got minus points sometimes, I guess you could only put one poster per window? Overall a very nice and fun game I did replay it a few times :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
