Hey all, I've participated in several game jams and wanted to pass on an insight I've noticed from them. I noticed a lot of people asking for more ratings, and most of them need to be downloaded.
If you want to get lots of ratings or feedback, make your game HTML5/WebGL so it can be played in the web browser. Most people are hesitant to download unknown software from a jam onto their computer, bc of the threat of malware & viruses. (think crypto miners, key loggers, & even ransomware).
If you make it playable on web, people are much more open to playing and rating it (I get about 2-5x as much feedback when I upload an HTML5 game than when I upload a local game like from unreal 5)
