Meh, I'm not a huge fan of this one (though I really loved several of the rejected ones), I've got a couple vague ideas but nothing really stands out to me in terms of gameplay, at least not on a small enough scale to be useful for LD...
We'll see, one of my vague ideas is starting to grow on me (as in, as I type this; I'm probably going to decide to try it), but it'll really rest on the strength of design for individual moments (moments which may have some tricky programming/asset creation associated with them) rather than single central element, so I have no idea if there'll be enough time to make it really worth it.
