Indeed they are, the Apple ][e levels are in a java version of the games on github: https://github.com/SimonHung/LodeRunner.

Legend has it that Doug Smith wrote the level designer and got the kids in his neighbourhood to work on extra level. If true I'd bet it's one of the kids initials.

The levels technically have one extra layer at the bottom, which is always a Block like character. So there is no need to store that with the level data. Good to keep in mind however. To get the Scores and last layer in the screen needs to shift up by 1 block.

I've mocked up the first level with all the details required in game, and it all looks convincingly Lode Runner.

I was thinking of putting the score-line 1 lower so I don't need an extra check on outofscreen-character.
( it is here a halfstone, not full from unbreakable brick)

Yes, the half stone is in keeping with better visual versions of the game. A full block would start to look a little strange, particularly when full unbreakable stones are on the bottom row.

Well, "Calculus Mazximus" is ready, time to pick up LODERUNNER again.
First movement bug solved. Setting back background of ladder went wrong.

Well,

have a first walk-around and let me here your comments. Speed, movement ok? etc....

Controls:
Q=up
A=down
5=left
6=right

Well, in fact IN-ports it is.
