Wonderful IMPROVEMENT PROPOSAL

This app is really fun and not too easy. I like the design very good and the exercises are also quite versatile. I like most the "level system" with the different characters. The music matches the app and not interfere. The price is reasonable and the app runs smoothly on my Sony Xperia Z2.

Conclusion: strong buy recommendation & *****! :-)

It would be cool to know how much of it is better / worse than the average. You also get quite fast 3 stars for the exercises. Had never less than 3 and therefore had to not make a special effort or practice. I play the level again only to get a better score.
