Challenging? No. Entertaining? Enormously. Bonus points for including a separate music mute button, and using a background song that didn't require it. I call awesome game smothered in awesome sauce.
Inconsistently challenging, but a fun little game. Level select and undo would improve it greatly, moves used tracking would be nice, and selective music/effects mute would be icing. Despite all the grousing, not all the levels are (can be?) solved symmetrically. But yeah, there is some inherent repetition in many of the solutions. And why is it so much more fun to finish a puzzle with an unnecessary rebound...? : )
