Hello
after i followed your unpacking steps, my dosbox said, it is still somehow compressed...
than i downloaded this:
https://github.com/otya128/winevdm/releases
but the installer crashes less than a second after the doubleclick on the file-icon.
than i found that you linked an extracted and than zipped version of the labyrinth game.
And this works in my dosbox.
I only find a few little bugs about the function of making images of mazes:
-the list-box for selecting wall-patterns does not show previews, only, the selected blue underlayed item shows a preview.
-when pasted in the old paint tool inside my dosbox, the repeat-block-size of the pattern does not match the maze-block-size.
Looks like the patterns are fitted for 8x8 pixel blocks, but the maze, pasted in the paint-program is made out of 5x5 pixel blocks.
while the pattern horizontally shifts through the too small maze-blocks, it's last three pixel-rows are cut off at the bottom of every maze-block.
