Essentially I just need to create a basic animation system, and then overlay this over the main Squiffy engine. Graphical objects take the place of conventional links, and using HTML / CSS these can be accurately embedded into the world as interactive items. Equally, the way in which Squiffy works would allow me to use it for all the required scripting and graphical updates.
Very early days, but yesterday I threw together a basic system to handle player movement. It's very crude at present and not yet making use of Squiffy, but it will hopefully give you an idea of what I'm aiming for.
I'm doing this as more of a thought exercise rather than to create a specific game (as there are dedicated p&c engines), but thought I'd post for anyone interested in unique implementations of Squiffy.
I've noticed on the Quest forum there is a lot of custom development, so maybe we can push Squiffy a bit further here.
