It seems that I got offered a new (redacted text), so this is likely to be the last entry of my journal. My job will be (redacted text)!

The main building is just like the others. On my first day, I came into Reception with my orange pass. (They have hardened the exits here, so I left with an orange pass at the end of the day too.)

Then it was straight off to Inaugurations - where I was (redacted text)! I needed the orange pass for that - I was nearly late for it on my first day too - having to switch my pass more than once only to end up with an orange one again..

After getting inaugurated, I was sent to Induction, having to pick up a blue pass on the way, where I was met by a charming young man who then sat me through an hour of the most boring (redacted text) I have ever witnessed.

Then off to the one room found in every (redacted text)! A quick slurp of uncle Joe at the (redacted text). It's really great there - but they serve blue pass holders only, and there's a long queue in and out of it.

Then I rushed through (redacted text) at the Briefing Room with a green (redacted text) though I nearly got lost. My line manager (redacted text).

Towards the end of the day, I visited my new office – the (redacted text) which needs a blue pass. Then it was straight back and out the front door at the end of a (redacted text) day.

Copying my assumptions about the rules, and observations from the previous puzzle:

- The squares on the grid edges are the doors with a pass colour that you need to pass from one room to another.
- The paired arrows in each cell represent exchanging your pass for a different colour.
- Multiple swaps can be performed in a room.

Observations:

- If a room has only one door of a particular colour, and no exchange-arrows with that colour, then that room represents a dead-end for that pass colour.

- If a room has only one exchange arrow with a particular colour, and no doors of that colour, then that exchange-arrow can be ignored.

- These rules can be applied iteratively, and a number of paths (and some entire rooms) can be marked as unusable dead-ends.

With all those options crossed out, we end up with the following map:
enter image description here

On to the puzzle:

The first few moves from reception are forced
E (To the Canteen)
Swap Orange-Red
E
Swap Red-Yellow-Green-Blue-Purple-Orange
N
Swap Orange-Red
W
Swap Red-Purple
W
Swap Purple-Blue
We now have a choice here, but the quickest was to Inaugurations is:
N, N
Swap Blue-Green
W,N,N
Swap Green-Blue
S
Swap Blue-Purple
N,E
Swap Purple-Blue-Yellow
E,E
Swap Yellow-Red-Blue-Orange-Purple-Green
N
Swap Green-Yellow-Blue-Red
W (To Inaugurations)
Swap Red-Green-Orange, and we have the right pass for our first goal.

This is a dead end, so we have to backtrack several moves before going anywhere new.
Swap Orange-Green-Red
E
Swap Red-Blue-Yellow-Green
S
Swap Green-Purple-Orange-Blue-Red-Yellow
W,W
Swap Yellow-Blue-Purple
W,S
Swap Purple-Blue
N
Swap Blue-Green
S
Here we diverge from our outbound route
W,S,W
Swap Green-Yellow
W,S
Swap Yellow-Purple
S,S (To Briefing Room, briefly)
W,W,N (To Induction, but we haven't got the right coloured pass yet, and can't get it here.)
Swap Purple-Green-Red
S
Swap Red-Yellow-Orange-Green-Blue
N (Back to Induction, with the correct pass this time for our second goal).

Again, we are in a dead-end and need to backtrack.
S
Swap Blue-Green-Orange-Yellow-Red
N
Swap Red-Green-Purple
S,E,E (Through the Briefing Room again)
N,N
There are other possible routes from here, but it is quicker to continue backtracking.
Swap Purple-Yellow
N,E
Swap Yellow-Green
E,N
Now we diverge again.
Swap Green-Blue-Red-Purple-Yellow
S
Swap Yellow-Blue-Purple
E,S
Swap Purple-Yellow
E,S
Swap Yellow-Orange-Red
S (To Reception)
Swap Red-Green-Yellow
E (To Canteen)
Swap Yellow-Green-Blue and we have reached our third goal.

Again, this is a dead-end, so backtracking is required.
The route here isn't entirely forced, but we've already passed through the Briefing Room, and the simplest way back there is to retrace our steps with a minor diversion at the end to make sure we have the correct pass.
Swap Blue-Green-Yellow
W (To Reception)
Swap Yellow-Green-Red
N
Swap Red-Orange-Yellow
N,W
Swap Yellow-Purple
N,W
Swap Purple-Blue-Yellow
N
Swap Yellow-Purple-Red-Blue-Green
S,W
Swap Green-Yellow
W,S
(Here we diverge from our Induction route.)
W
Swap Yellow-Green
S
Swap Green-Blue-Orange
S
Swap Orange-Blue-Red-Yellow-Green
E (To the Briefing Room with the correct pass for our fourth goal.)

Again, we are in a dead-end, so back we go...
W
Swap Green-Yellow-Red-Blue-Orange
N
Swap Orange-Blue-Green
N
Swap Green-Yellow
E,N,E
Swap Yellow-Green
E,N
Here we diverge
Swap Green-Blue-Red-Purple-Orange
W,W,W
Swap Orange-Green-Red-Blue
W,S
Swap Blue-Purple
N,N (To the Broom Cupboard, but lacking the correct pass)
N
Swap Purple-Red-Blue
S (To our luxurious officethe Broom Cupboard with the correct pass.)

Finally it's another bunch of backtracking along well-trod paths to find our way to Reception.
N
Swap Blue-Red-Purple
S (through the Broom Cupboard again)
S,S
Swap Purple-Blue
N,E
Swap Blue-Red-Green-Orange
E,E,E
Swap Orange-Purple-Red-Blue-Green
E,S,E
Swap Green-Blue
S,S
Swap Blue-Purple
E
Swap Purple-Green-Red
E
Swap Red-Orange
S
Swap Orange-Purple-Blue-Green-Yellow-Red
W (To the Canteen)
Swap Red-Orange
W (Back to Reception finally at the end of a long day.)

    $\begingroup$ Gold star!. Beautifully done. I do hope you found this a bit more interesting? Is it 'tough enough', considering it is, essentially, nothing more than a graphical maze? $\endgroup$
