Yeah, the game needs a lot more time to cook... or does it? Maybe it just needs fewer ingredients. You should add only the necessary content to make it playable. Disco Elysium has a lot of systems, and they don’t work well because of what they are but because of the effort and design put into them. That level of quality can’t be achieved in three days by a solo beginner game dev, but that’s okay—you probably learned a lot from this.
I wish you good luck in your future projects (be careful with scope creep), and congratulations on taking up the challenge of trying to complete a game in three days
