I'd just rather it not show choices I can't pick because it's not a choice in that situation. Even in a demo.
Like an alternative would be to have the non-active choices be a different colour so I know in the demo 'this would be an option and we're leaving it visible but not much point clicking it'. As it is right now I just got through lots and lots of 'this isn't available, this isn't, this isn't' and it killed my drive to continue the demo because I felt like it was unclear what would be possible to engage with.
For me, I engage in the game by trying to see how I'd feel in that situation and picking what matches my feelings most, if the options are limited in this way, I stop being able to be in my feelings and connecting with the character, because I'm constantly going 'Wait what?'.
So I will only be able to play this when either it's finished or the demo has the non-active options more clearly labelled before I click them. Otherwise it feels like it's saying 'NO! No choices. Only unspecified choice!' [insert that lil dog meme lol].
I'm sure they will have great choices when it's done and I don't doubt there's choices throughout but as it stands right now, as far as I got, it gave the impression you will only have one path and it won't let you know until you pick a choice that you picked the 'wrong' one, and then response as thought you picked another one. It's just stressful for me personally lol
