Sadly no games using UE made it past day 2. Nobody wanted to take UE projects day 3. Ngl I'm bummed out because my D1 project was UE and I was really proud of it.
Good news is nothing is stopping you from doing something with your prototype once the jam is over.
I wanted to do paint kart, i just haven't touched unreal in yeeeears
I was thinking about doing it but I was using unreal5.1 and didnt have the space.
