I was skeptical when I first joined how much time I would be able to put in, or if it was a good idea for me to join at all. I got a working prototype, but I've got another game jam tomorrow and don't think I can put in more time at this point without being in really poor shape for the team.
I did learn some interesting new things with Three.js for Web 3D, and got a bit more comfortable with Blender. I think in the future, I'll avoid doing Game Jams alone though, as that seems to be where I fall behind the most.
I still submitted the prototype, and you can find it here if you're curious. I don't think the issue was scope, since most of the work you see I did in the course of 1 day (I've worked on this about 13 hours today); I think I need to be careful of taking on more projects right now and collaborate more in teams, though.
Thanks for the opportunity, and I wish everyone else here the best with their submissions!
