By moving the positions of cats, as long as three or more cats are arranged, the elimination conditions can be achieved.
In each level, you have the opportunity to use cat gold coins to purchase specific props, which can achieve smooth elimination effects under limited clearance conditions.
You can, at the beginning of the level, click on the props to use them. If the number of props is 0, you can use cat gold coins to purchase them first and then click to use them again.
