Pretty sad that one of the buttons I think is to play are written in Chinese. Also when I hit the button to play first puzzle had to hit it several times before it got me there. Didn't even play a game uninstalled.
Too much time wasted between levels, 5-10 seconds per level waiting for effects or ads. Too many ads, Ads at the bottom of the screen, ads that pop up during game and interrupts game, and ads implemented IN the actual game advertising micro-transactions. Free games need ads to generate profit but this is way too obtrusive and desperate.
