I played through your Demo/Proof of Concept.
I basically liked it, not terribly much, but did like, which was surprising actually, since essentially that game was choose your adventure game, which in its core isnt very interesting usually, and I do think it would be good to add bit more stuff to make it less Choose your advenuter. Like pick items, and then use them at right locations.
Somehow your writing was very good, which is surprising, since when I look at it, it doesnt seem so, it doesnt look like it is good at all actually, but when I played the game, that text immersed me into the game, and I liked following the story forward. So strangely, your text looks like bad, but it is actually very good.
What I think worked in your game, was the educational aspect of the game. As in, you were showing me some real art pieces. Looked like they might be even from some certain museum, are they? For if they are, then there was actually one thing I was very much wanting, for the game to start with text "Somewhere in the British Museum..." or whatever the location is.
For basically, while Choose your Adventure isnt too thrilling a concept, if it however would be tied on an educational game, then that educational aspect of educating me a bit about these art pieces, would be enough of a reason to accpet Choose your Adventure as the game method to make me happily play it.
Now, while I got captured by the text and the story at beginning of game, I did however feel less interested towards the end of the demo. But I dont think this was so much to do with the text, but rather because I was wanting bit more to play. Like pick item from one location, and use it on another. Say the donation box, make it locked, and make me get the key from somewhere, then use the key to open the donation box.
But all in all, I could see this game work. I could even see myself buying this game, if it does have that educational aspect into it.
And I really liked the story. It brought something interesting in that this historical statue is looking for its sisters, and the thought that this statue character is basically from somewhere from time of BC and been constrained access to outside world made it also interesting plot, as in, how is this statue going to be able to work its way in todays world.
