I can't believe I was actually able to do the jigsaw deductively. Probably should have paid more attention to the image when choosing it. I think the music could have been a bit longer so that it didn't feel so repetitive.
Thanks for the feedback..
While doing the puzzle, arrow in right bottom shows a menu which also has a hint button to show reference image. I’ll make it highlight if user is taking time in between steps I guess, to get the player’s attention.
I’ll look for a longer background score in public domain.
