I'm really sorry, but I've just not had much time or motivation for anything - I've not even opened GLB to code since I completed my Advent game at the end of November. That's two months ago. I've got commercial games from Christmas 2013 (and plenty more besides) that are still wrapped in cellophane. Time has not been on my side.
I don't think there's a lack of interest, just some things take priorities or there's a lack of time.
We're not a big community anymore, so feedback is often limited - I've released/mentioned stuff here and got no feedback; that doesn't mean that nobody cares though.
Perhaps releasing your demo/game on sites that cater for this type of game will bring better results.
