Hi,
tested and rated
enjoyed the game, I agree it is slightly hard, for me the main game breaker was a delay for arrows when tapped.
I can't tell if that delay is because of it was old iphone4 I tested...
So I see the new color coming, I tap it, no rotation for arrow about 0,5-1 sec and then the rotation happens while I tapped again thinking I missed it, so the arrow rotates twice and I lose
Other than that great game with nice atmosphere.
