Do you feel this level is hard to complete? Don’t worry, and just start it straight from the shoulder!
Make a combination with a boxing bag to punch it, and it won’t take much effort to get the result!
The number by the boxing bag at the top is the number of times you need to "punch" a boxing bag. "Remove" the boxing bag as a part of a line or a section to "punch" it. You can punch them in any order and any combination. Once you have punched boxing bags enough times, they are removed from the game field.
Good luck!
