Well, this sure hasn't gone great.
The Good News:
I have been able to come up with what I want in the demo, so it's now just a manner of making it in time. I've figured out the presentation and first work you'll step into so to say.
The Bad News.
I have no clue how to actually get it done. My main experties lies with engines that don't really function that well for what I wish to do, which is a more standard MYST clone with pointing, clicking and the wonders of FMV.
Anyhow, should I find as I'm working tonight that there's no use trying to make this a playable demo before the Jam ends, I will likely just make a little video demonstration as a pitch of the general concept instead, as I have that down. Concept art and such should start to drop in here as I get down to producing stuff later tonight either way. I think people will like the intro idea at least.
