Good, but there is a glitch – White Tiles 4 : Piano Master ( Don't Touch the White Tile and Trivia games ) - Free Review

I really love this game. I play it all the time. But there is one glitch. On Piano Tiles 2 mode, the screen freezes up just for a nanosecond, but it messes me up. Please fix this. But over all a great app.
