找心脏 Find the heart

[this game is inspired by the classic game:BALLANCE.]
"Find the heart" is a simple pixel wind physics puzzle game. There are real physical effects in the game. Players explore the world by controlling the rolling of balls with various materials. At each level, there is a heart hidden, which can hardly be found. However, if all the energy balls in the level are collected, a prompt will be displayed after passing the level. With this tip, it's much easier to find the heart. Even so, to find the heart, players still need to have extraordinary ideas and precise operations. This game is very small and there are not many levels, but it may take more time and thought than many other games to find all the hearts.
Can you find these hearts?
