A very cute and relaxing game! The art/graphics are very nice, and the music was a perfect fit.
The only thing I kinda missed was the ability to use a hit while in the puzzle, and not just at the start of the stage, but all and all very well done!
I think they meant "hint" because I had the same feeling of wanting to have a hint after tinkering with the puzzle for a while instead of taking a hint before I even got to see if the puzzle was a hard one!
