This is a puzzle game, but relaxing music can relieve players' tense state and better immerse them in thinking. The operation of this game is very simple. Players first need to think calmly, have a general understanding of the entire scene, and then come up with a rough route, using every mechanism as much as possible, because the designer will not give you useless mechanisms, which is quite generous. In addition, in situations where the situation cannot be opened up, it is advisable to create opportunities through sliding and leveraging, which often have unexpected effects.
