Very frustrating!!!!

I purchased this application for my 4year old grandsons. I attempted to try it before showing them. The step of pressing a specific colored dot a given number of times is EXTREMELY frustrating as it is not responsive. Sometimes it requires numerous attempts before the puzzle appears. The last time I attempted to open it I could not get passed the dots. The free apps have worked better than this. Very disappointed.
