Wow, the concept/story was very interesting and I think quite original for the jam. But as mentioned, there's not much gameplay here. And what you can do, is hard to make sense out of.
Still, it seems like you have interesting ideas so, as you've already said, next time make better planning for your actual gameplay and then add story where you can. I'm sure you'll do great!
And congrats on finishing your 1st gamejam! :D
