Thank you Avery for everything you are doing for this small community.

I have shown engine protos before, but it was not a real game, just a few bouncing balls.

If there is no DOS, you can play the single built-in level.
|
||||
|
||||
With DOS, the game tries to load `LEVELnnn.DAT` file, starting from `LEVEL001.DAT` from the current directory.
|
||||
|
||||
The levels can be edited on Atari with the enclosed `ED.COM` editor or a PC (end line characters can be LF, CRFL or ATASCII EOL).

### Level file format:
|

line 1: number of balls to be hit for the level to succeed
|

line 1: number of bricks to be hit for the level to succeed
|
||||
|

line 2: `1` means single pixel width of the pattern, `2` double pixel width
|

line 2: `1` means single pixel width of the brick, `2` double pixel width
|
||||

the following lines define the level. Any character is a pixel, space is a space, EOL is the end of line.

|

|

Important! Any error in the level definition causes the game to return to level 000, so if you make a mistake in `LEVEL004.DAT`,
|
||||
the files `LEVEL005.DAT` and `LEVEL006.DAT` will never be displayed.

T022: when balls disappear, their traces should disappear, too, even when a new ball is NOT created

now the dead pixels disappear only when a new ball is created.

It has been done by expanding the bottom area, so the balls are going down.
