At the moment there is no reward for performance like achieving very high score.
So in my opinion when someone achieves blue sugar stars the player must be rewarded with some boosters like 1 UFO.
and also the blue sugar stars should have to give more power to the photo frame.
At the moment they give same power to photo frame like normal stars.
This will help and inspire the players to go back to levels and clear it with high score. To obtain sugar stars.
