Blobbo got a mention on facebook recently.

looks like I hit the screenshot at the wrong momenton the last map!

I don't know if it's my copy, or if it's a glitch in the code, but the bottom left has an extra 1/4 dot outside the maze, making clearing everything impossible.

Designing new mazes outgh to be possible. Once loaded into memory, the screens appear at:8457,8717,89D7 and 8C97 in memory. There's no form of compession, just the byte codes for the various map pieces.

Emclosed a copy of the disassembled program code. Because it's machine decoded the labels are mostly of the Lxxxx type.

It's from the version on Magrom, so formatted as a .RUN file instad of the more usual BASIC & assembler within an MTX.
