Congratulations on your first gamejam!
I think you did great and I hope you continue making games in the future!
I think the only thing I would have wanted to see would be some story elements to tie into the narrative fiction theme. Even subtle things would have been nice like idle lines from our character that hint at a larger world, or maybe some texts that trigger on item pick up, but besides that, this was a great first jam, and it's awesome you managed to get it done on your own!
Good job!
