I found the old NWComputing website, that contains some answers that could be very useful to replay Wetlands:

```
These are some of the most common technical and game questions asked about Wetlands.

Q: While playing Wetlands, the game suddenly drops to DOS/Windows 95 and
says "Error writing temporary file."

A: Try increasing the FILES= value in your config.sys to 80 or 100.
If you can decrease it to a lower value without causing the game to
crash, then you can save a little memory.


Q: I keep running out of time at the Oxygen Facility.

A: Make sure you are going in this pattern:

Down, Down, Up, Up, Down, Down, Down, Up, Up, Up


Q: I am going in the correct pattern, and I still can't get past the
Oxygen Facility.

A: You must have a 486DX2-66 or better CPU to play this game. If you
have a 486DX2-66 and you still don't have enough time, get the
WETUP11.EXE update as it will increase the level time from 5 minutes to
7 minutes.


Q: How do I get past the Xi Colony hoverbike scene?

A: Straight, right, right/up, right, left, right/down, straight


Q: I can't get past the Ancient Ruins. Which way do you go?

A: Right, right, right, left.
```

I don't know if the correct level sequences are found somewhere else.
