I've just had a look at last week's mazes. Andrea's is excellent. The
shortest path, divided into groups of 5 moves by commas, seems to be
ddudu, llr (or ddu) ld, uurlr, dudud, lulrl, rdurl, ur which is 32
steps.

Hi! I like the 12345 maze.
My Answer of Andrea's 12345 maze is 32 moves shown by the attached file.

Linear in the sense that there was only one place to take the '5' move
in each case, if moves back to a previous '5' location are disallowed.

I finally solved Andrea Gilbert's 12345 maze by backsolving the last
several steps.
The finish can only be reached by a 1 or 2 move.
A 1 move must have been preceded by a 5 move, which must end at an edge of
the board in a line with no blockers. (Note that there are only 4 such
lines, so only 8 such states to consider, or 9 if you include the start
state.)
None of the spaces 1 away from the finish fits this description, so the
finish must be reached by a 2 move, which was preceded by a 1 move from one
of the 9 states mentioned above. Only one pair of last two moves allows
this: Up 1, Right 2.
The two moves before that could only be Right 4, Left 5.
The next previous move could have been Left 3 or Up 3. However, there is no
12 path from a startorafter5move state that could lead to the Left 3
move, and only one for the Up 3 move, so the next 3 previous moves were
Right 1, Down 2, Up 3.
This was a state I had reached going forward, so the maze was solved.
Down 1, Down 2, Up 3, Down 4, Up 5
Left 1, Left 2, Right 3, Left 4, Down 5
Up 1, Up 2, Right 3, Left 4, Right 5
Down 1, Up 2, Down 3, Up 4, Down 5
Left 1, Up 2, Left 3, Right 4, Left 5
Right 1, Down 2, Up 3, Right 4, Left 5
Up 1, Right 2
An interesting way to think of this is a 6 move solution in a maze with 9
states. The moves are just complicated (like in the cooperation maze,
except there, you have a long path of complicated moves  and no, I haven't
solved the new one yet).
The solution visits 7 of the possible 9 states. The other two states, as it
turns out, are unreachable, although one of them could be reached if the
start square was elsewhere.
I also solved the noneuclidean maze. Tricky, but not entirely different
than some game maps I've seen. Once I figured out that the distorted
perspective was only a distraction, it wasn't too hard, though it still took
me a while to find my way to the second green room.
