After playing 20 levels, i texted my sister to trial the game also. I love puzzles and enjoyed playing the levels. I agree with others, in that a hint button would have been a necessary component to this game. I did have to click on the Help button after the first few levels just so i could peek for a starting point. I mute sound in all games so i cant comment on the quality.
I will definitely get the game on the next 2 for 1 sale.
Love it ... when I got to the butterfly, I was truly entertained. Before that, the first few puzzles were warm-ups, letting u get use to the mechanics.
