The use of the command EXAMINE is very sparse in this game. you can use it only at 4 occasions. I looked at your map. Can you tell me where exactly you are stuck?

I've made a map of the beginning of the game (the total game has 158 locations. I'll finish it one of these days when I have more time). As you can see you missed the locations inside the building (to obtain the manual). You have to use the submarine to reach the beach. From there you have still a long way to go :)

Thanks, Alex!

I know I need to get into the building (locations 35 to 39) but I couldn't work out the syntax to do it, which led to frustration. I have the small key (from location 20), do you know if that's the right one and what the syntax is to get in the building?

I finished the game, but the original version has two bugs which makes it impossible to finish the game:

-You can't enter the building. I suppose you should be able to open it with the key, but this has been forgotten to program in the game (you can only go in when aa%=1 and this never happens). However to finish the game you don't need the manual.
-You can only solve this game if you are able to carry 5 objects, but the problem is you can carry only 3. Although line 560 of the code shows it was the original intention to be able to carry 5 objects. This bug makes it impossible to return to the last locations after you've obtained the knife. Before you use the jetpack you need to carry the credit card, key, helmet, bullet and revolver.

Both these things can be easily changed in the code.

I wrote a fixed file which makes it possible to solve the game, but I'm not very familiar with the BBC computer. Anyone who can tell me how to unlock a locked file so I can replace it with the fixed version?

I finished and uploaded the map and walkthrough.

Thanks (again) Alex. I'm an old-school BBC coder so I'll have a go.

I suspected there were bugs in it - how frustrating!
