Great job! Reminds me of a fire game I played in Age of Wushu. Nice music and sound.
A few suggestions. Please take them with a grain of salt.
Mouse over graphic highlight and animation would be nice
larger tile sizes would be cool
You may want to do a tutorial few levels before putting on FGL market.
it would be nice to know what the absolute minimum moves to victory is.
Not sure solve button is the fast way to the end, could be wrong.
Might be nice to have a tool tip for hint. I notice it actually progresses you rather than gives you a hint.
Art work could be a bit more tied together. (ie green led with fractals with flame buttons, don't quite match up).
But again great stuff!!! Thank you for sharing.
