Interesting
I played for a while and it never was a challenge, though it‘s smooth enough to qualify as a time killer when you‘re waiting at the dentist. Some more variation would be welcome though. The ads are less frequent than in the other games by the same publisher, which makes the experience quite pleasing in comparison. For some reason the sounds and ambient music were disabled when I first started it. Also, disabling the music with the button doesn‘t work. The sound accompanying the tapping of the pieces is quite harsh and loud compared to the calmness of the music: a softer one would be much more welcome.
