I see the situation painful, to the jams I see that they need more information about the necessary operating system requirements, or that these people need a more updated computing education (I think it has cut much morale and education to create smartphones or something similar). By the way in what game jams this happens? give me some examples, please.
It just happened in our Slime Jam https://itch.io/jam/slime-studio-jam In our discord server. Most games are clearly marked.
