I have a puzzle idea based on DROD. The goal is to reconstruct the starting layout of a tiny room (5x5 or smaller) containing Beethro, one roach, and a few obstacles. In each puzzle, you are given two or three sequences of moves which successfully kill the roach from the starting layout. The last move in each sequence is a killing move. You are also given Beethro's starting orientation and info about what else is in the room.

Example Puzzle:
Beethro starts facing N. There is one wall tile.
The move sequences are 'W3' and '23'.

Example Solution:


For all the puzzles below, neither Beethro nor the roach start on a force arrow.

Puzzle 1:
Beethro starts facing N. There are three wall tiles.
The move sequences are 'Q82', '226', and '891'.

Puzzle 2:
Beethro starts facing SE. There are two wall tiles and one force arrow.
The move sequences are '856', '591', and 'Q9W'.

Puzzle 3:
Beethro starts facing NE. There is one wall tile and two force arrows facing the same direction.
The move sequences are '25W', '992', and 'W96'.

Puzzle 4:
Beethro starts facing S. There are three force arrows, none of them pointing diagonally.
The move sequences are '4664', '9W3', and '1Q4'.

Puzzle 5:
Beethro starts facing N. There is one wall tile and two force arrows.
The move sequences are '643' and 'Q46Q'.

When posting a solution, please put it in a secret tag.

(I am reasonalby sure that the solutions are unique, but it is possible I overlooked something.)

Hmmm. Well, okay, I'll give it a try. I'll be using the following key:

#:    Wall
.:    Floor
B:    Beethro
R:    Roach
^v<>: Non-Diagonal Force Arrows
\|/-: Beethro's Sword (if in an empty square)
?:    Unimportant floor tile

I use the last symbol for any map where I didn't need all the Walls and Force Arrows given. I might have missed some optimizations with the puzzles, but these were the setups I arrived at.

Puzzle 1
Puzzle 2
Puzzle 3
Puzzle 4
Puzzle 5
Anyways, nice setup of puzzles. In a way, it's kinda similar to the sort of thing Jacob was doing with his Darkness level in Reflections, but approaching from the architecture side rather than the solving side.
