Glad to hear it, i wouldn't be spending my time writing up a review or bug report if i didn't think there was potential here :)
While i think it's very cool to keep it free, i do think people should be compensated for their efforts, so my review is from the perspective that you'll be seeking to make a product people would gladly pay for, all games, even free ones, are viewed as a matter of quality vs investment, even if it's only time investment.
That being said, i shall wait patiently for your next update to see how this develops, good luck!
