Ive been going back to this course after ive been away for some time. now ive tried to tune the game so theres more balls, and you can loose balls until the last one. if that one goes past the paddle you lose, but ive found that when i play, if two or more balls seems to hit the same block at the same time, they all detract a block from the serialized field, so the game thinks theres fewer blocks in play than there actualy is.
the ballcounter is also bugged sometimes as it dont count all balls at the start some times. ive gone about the counter the same way as the blockcounter in the course
ive added debug so you can see that two different balls destroy the same block/brick
