I also fixed it this way, but after watching the video i decided to also add the code to the LevelManager.cs too, maybe the breakableCount carries over from one level to the next but i just have not tested to see if this is the case, so added the code as a safety measure.
I also fixed it that way. But then realised it could be problematic if you want to implement a concept where you have several attempts to go through a level and want to keep the brick count after loosing one attempt. Because every time it will be reseted to 0.
