I’ve played way too many gradient sort games, so I’d like to think I know what I’m doing when it comes to a good gradient sort game. I had two main issues with this one, which was that it would roll an ad (that you could skip in >5 seconds) that would ALWAYS stop my music, without fail. I am a person that likes to have music in the background, and this aspect just made me really grumpy. Also the calibre of the ads was concerning, with rather risky ads rolling about with an app aimed at kids 4+. The other main issue I had was the slow reactions to my movements of the colour tiles. I would go to swipe around the tiles, and it would only register 75% of them because I was going faster than a snail’s pace. The accuracy of the touch input was also a little off, it would read a tap as a swipe and vice versa.
