Use your fingers to cut the diamonds and other important objects, but watch out for bombs and poison bottles.
If you cut the diamonds fast enough without hitting other items, you will receive combos that will increase your points and give you more time.
Many items will only become available to you over time. Combos and other circumstances will gradually unlock them. How exactly is a secret. Some of them give you more time, some more points, or they give you extra health. On top of that, there are also some cool backgrounds that you can earn. This makes for a little more variety in the game.
The app is ad-free and there are no subscriptions or in-app purchases. You pay a small price for this game and you will be spared from annoying interruptions.
