Absolutely LOVE this game.

I took my time, remained patient and practiced, so eventually i got 3 stars in EVERY level. You can choose "levels" in the menu and go back and replay each level whenever you want and as many times as you wish. The game makes you think: plan your moves and practice for coordination. I found using two hands helped sometimes-one on each side of the screen. I think it was worth every penny. I also paid an extra 99 cents to have the hints available whenever I wanted. That helped. You can replay each level without penalty if you choose "restart level" from the menu.
Be patient and just have FUN with this game.
