I. A more perfect model to copy = less experiments
One of the things I’ve found jaunting through adventure games that’s … not exactly “disappointing”, but I can’t think of a better word … is that unlike CRPG history, there doesn’t seem to be that many early unique experiments. CRPGs sprang from pencil-and-paper where the computer equivalent was unclear, but most everyone in early adventure games seemed determined to copy Woods and Crowther.
There is one exception, and the game is so obscure it is quite possible I’m the first one who has played it since the 1980s.

SoftSide Magazine, October 1978.
Lance Micklus later on went to publish Dog Star Adventure in 1979, which appears to be the first published type-in text adventure. Treasure Hunt I’d call marginally an adventure, but in a form generally unrecognizable because rather than branching off Adventure, it has roots in Hunt the Wumpus.
II. A brief analysis of Wumpus
Hunt the Wumpus is a 1972 offering by Gregory Yob. Jimmy Maher has a two-part series on the full history here and here.
To get into Treasure Hunt — which has some of the same concepts in the gameplay — I thought a transcript of Wumpus with analysis might help. (I used the Z-code version.)
You are in room 5
Tunnels lead to 1 4 6
Shoot, Move or Quit (S-M-Q)? m
Where to? 6
I’m playing on the classic “squashed dodecahedron” from the original game.
It helps to have pre-mapped what room numbers correspond to what places on the map, although the dodecahedron structure makes it possible to “feel out” the geography off the cuff.
You are in room 6
Tunnels lead to 5 7 15
Shoot, Move or Quit (S-M-Q)? m
Where to? 15I feel a draft!
You are in room 15
Tunnels lead to 6 14 16
Shoot, Move or Quit (S-M-Q)? m
Where to? 14
The “draft” indicates a room nearby has a bottomless pit. Since I came from room 6, the draft has to be either rooms 14 or 16.
A careful strategy would be to note that as a sort of logic puzzle condition, go back to 6, and save the knowledge for later. For instance, if a later room has no draft but room 14 adjacent, that means room 14 is safe.
In order to keep this transcript short, I foolishly plunge ahead to 14:
You are in room 14
Tunnels lead to 4 13 15
Shoot, Move or Quit (S-M-Q)? m
Where to? 13
Risky! But now I know the pit has to be in 16.
You are in room 13
Tunnels lead to 12 14 20
Shoot, Move or Quit (S-M-Q)? m
Where to? 29
Not possible – Where to? 20I feel a draft!
I smell a wumpus!
You are in room 20
Tunnels lead to 13 16 19
Since 16 is the “draft” and we came from 13, 19 has to be the wumpus. Time to fire a shot:
Shoot, Move or Quit (S-M-Q)? s
No. of rooms (0-5)? 1
Room #? 19
19
Aha! You got the wumpus!Hee hee hee – the wumpus’ll get you the next time!
There’s more to the game — the wumpus can wake up, you can fire the arrow through multiple rooms, and there are “bats” that can carry you around — but this is enough of an introduction because things are about to get much more complicated.
III. The Lumus Caves
Imagine Wumpus having treasures you have to find.
If you bought the game it came with a map, but I had to resort to making my own. I have no idea if it is something sensible like “a dodecahedron only larger” or “a moebius strip with an extra twist” so my version is a bit of a mess.
This definitely reflects one of the downfalls of non-compass mapping — it’s hard to get relative positioning right on a complicated map. Should this particular branch go right or left on the map? I didn’t know until I got farther and had to erase and redraw.
IV. How items work
YOU’RE IN CAVE 2 WHICH LEADS TO:
CAVE 1
CAVE 4
CAVE 5THIS CAVE HAS GOLD COINS IN IT.
DO YOU WANT TO TAKE IT WITH YOU,
TYPE 1 FOR YES, OTHERWISE TYPE 2? 1
O.K. YOU’VE GOT GOLD COINS.
I should emphasize that even though the map is fixed, everything inside the rooms is randomly placed. In a different game the gold coins might be in room 63.
WHAT CAVE DO YOU WANT TO EXPLORE NEXT? 5
YOU’RE IN CAVE 5 WHICH LEADS TO:
CAVE 2
CAVE 10
CAVE 11YOU’RE CARRYING:
GOLD COINSTHIS CAVE HAS A MAGIC WAND IN IT.
DO YOU WANT TO TAKE IT WITH YOU,
TYPE 1 FOR YES, OTHERWISE TYPE 2? 1
O.K. YOU’VE GOT A MAGIC WAND.
WHAT CAVE DO YOU WANT TO EXPLORE NEXT?
Important points to note:
a.) There’s at most one object to a room. When entering a room with a portable object, you can either take it with you or leave it be.
b.) Leaving it be is more interesting than you might think, because there’s a three-object inventory limit. If you go back to the entrance of the cave (room 0) you will deposit all your treasures, but won’t be able to take any back. This is important because …
c.) …some treasures double as puzzle solutions. For example, the gold coins can be used on a vending machine to get new lantern batteries (yes, Lance must have been familiar with Adventure) but since this is done automatically upon entering the appropriate room, it is better to note the gold coins on the map and get them when the lantern starts to run low.
V. Dangers
Just like Wumpus, there are obstacles that will kill you if you wander in the wrong room.
YOU’RE IN CAVE 20 WHICH LEADS TO:
CAVE 10
CAVE 40
CAVE 41THERE IS A PIT NEARBY. wATCH YOUR STEP.
YOU’RE CARRYING:
A NECKLACEWHAT CAVE DO YOU WANT TO EXPLORE NEXT? 41
SORRY, BUT I TRIED TO WARN YOU.
YOU FELL INTO A DEEP PIT AND KILLED YOURSELF !!!
READY

There are also potential cave collapses, a pirate that can steal your treasure, and a dragon.
VI. A puzzle example
There’s a room that has a barking noise. There’s also an invisible man looking for his dog, and he needs you to type the room number his dog is in and he’ll give you a $1000 bill. However, if you type the room the barking was heard in, you will fail.
It turns out — using Wumpus logic — the barking means the dog is in an _adjacent_ room. So to solve the puzzle you need to find three rooms the barking is coming from and triangulate.
(The “B” means “barking”. The red means a room with a danger notice, so there’s some adjacent room that is deadly or at least has an enemy that needs to be defeated by the right item.)
In any case, I’m not quite up to a successful run with 20 treasures, so I’ll save what will hopefully be a winning post (and the true secret to slaying a dragon) for next time.
