Hi Indee, I've been looking at a way to make a web browser version, it's currently not possible on Unreal Engine 5. I primarily use Unreal Engine 5 for my projects.
So if that's the case I won't be able to participate in future Jams, which honestly is a shame. I hope this can be rectified whether you will allow games to be submitted as a windows build (as I have done). Alternatively if UE5 implements a method to do so then I would make a web build.
Please let me know how you want to proceed with this occasion.
