I don't want to say never... but if I'm being honest with myself, that's the most likely answer. For now, I'm working on other projects in my free time. I'd like to return to Reflector someday, but I don't know when my current projects will wrap up, and when they do, something else might have me more excited.
All that said, the game's code and graphics are all open source, and anyone is free to fork the game and continue development if they want. (Note: the music and sfx are proprietary, but maybe an agreement could be reached with the composer/sound designer.)
