Hey Mugwump! So for the finished demo there won't be a whole lot in terms of gameplay, just some small extra things I'll be adding in to compliment whats already there :) For example, being able to interact with the jukebox etc. I'm hoping to take the demo further when I finish uni, and try start fleshing out a lot more of the gameplay, adding things like a survivability element with oxygen depletion and having to keep your character oxygenated. To be honest, I havn't thought much further along, I usually just add elements in as the project progresses :) Hope that answers your question!
