Great implementation, very enjoyable. Any chance that you will use this foundation to make an actual game (I mean, challenging, with scores/time/etc., and without the marketing component)?

I have always missed a worthy sucessor to Marble Madness. I have tried several partial implementations or demos inspired on it, like this, but never an actual full game with the same philosophy (maybe there's some I'm missing, in which case I would like to know, of course).
