So I was feeling a bit bored today, so I decided to try to get to LeChuck's ship in Secret without the Head of the Navigator, by making a map of those catacombs. So I used this method:
When I came into a room, I checked a large piece of paper on which I had sketched and numbered all rooms that I had already visited.
If I came into a room that wasn't on there, I sketched the room on the piece of paper and gave it a number. (starting with 2; room number 1 was the place were you enter the catacombs, with all the mushrooms).
On another piece of paper, I drew how all the rooms interconnected, making it a map.
However, I soon found out that every now and then you randomly end up back in room 1, and when you exit room 1 you end up in a completly random room. This was not much of a problem for the map: I just removed room 1 from it.
After about 30 minutes, I found out that the connections between rooms are one-way connections: if you exit room 2 to the right and end up on the left of room 3, that doesn't mean that if you exit room 3 to the left you'll end up on the right of room 2 again (infact you end up at the back of room 5). This meant my whole map was pretty much messed up, so I went to another system for the map: I looked at my sketches of the rooms, and gave each exit of each room a name (the right exit of room 2, becam 2R for example), and made a long list of all of these. Then after each one I put the exit it leads to (for example: 2R: 3L). Unfortunatly this meant I had to start all over again, because my original map had no indication of what way I took each of the connections.
So I filled them all in, figuring I'd find LeChuck's ship sooner or later. There were 20 rooms (counting room 1), so this took me a while, and my desk started looking more and more like I was playing Dungeons&Dragons.
After a while, I had them all filled in, only to find out none lead to LeChuck's ship. So I went to get the Head of the Navigator, and he led me around a few rooms, but when we exited room 4 to the right, we didn't end up at the right of room 17, but at LeChuck's ship. The bloody head cheats.
On a completly unrelated note: wouldn't it be cool to be a cleaner at the TellTale offices? You could use "TellTale Employee" as your title, and everyone would believe whatever you said because of it.
