Given the state that Godot is currently in, I feel that it's not very inclusive to categorically REQUIRE a build for Windows, and Linux, and Mac. While this is more inclusive to players, I would like to believe that jams are primarily about empowering creators.
Most developers I know have, at best, access to two of these at a time; many even just one. This requirement makes submission and testing an extreme hurdle for them - both in terms of time available to jam, and in terms of having access to the actual hardware and software licenses. Also, this puts an extra burden on developers dependent on assistive devices / features of a particular OS.
Regarding web exports as an alternative - games in Godot 4.x still have plenty of issues with their HTML5 web exports (and even entirely exclude games made in C#), which exacerbates this situation further.
Taking a step back, in the bigger picture the entire rules text reads so restrictive to me, I wonder what's supposed to be "wild" about this jam. I'd wager a considerable number of people felt intimidated or turned off by the language used and the rules described within.
I did, for sure.
...
I hope that this feedback doesn't come across too negatively, as it is meant in the best of intentions - and perhaps it can make future jams better. :)
