(I've just found out that the french guys from abandonware.org had already found the demo 2 years ago.)
About the demo:
There is no sound.
Using Demo.bat or RUNWITCH.BAT will play 3 gameplay recordings.
The arrow keys move the character, but only for debug purpose.
Correct movement:
Up: A
Down: Y (maybe Z)
Right: P
Left: O
Inventory: I (Use A,Y,P,O to navigate)
Cancel: ESC
Swing Sword/Interact: Space
W: Test message
Tab: "Command Entry Station" (Teleport and Variable manipulation)
Pressing F4 followed by F2 calls a map of the current location.
F8 pauses the game, F9 unpauses it.
F6 draws a debug grid,
F7 draws Z-indices(?) above enviroment sprites (trees, etc.)
F5 calls a sprite viewer, F6 switches the sprites.
F3 closes F-menus.
Self-Running demo:
On one of my old CDs (I think it was an issue of Power Play), I found a (damn rare) trailer for the unreleased RPG Witchwood by Team17:

The game uses an easy-to-use script language for dialogs/shops/etc. The extension of these files is .con (maybe "Conversation").
Many of these scripts feature additional information like design goals or implementation details.
Examples:
Code: Select all
; ****************
; ** **
; ** Sweet Shop **
; ** **
; ****************

;* Characterization
;* ================
;*
;* This is the bloke who does the Mr Kipling advert. Can the actors do this
;* voice and get away with it? Put in a but of Richie Benno(? not sure what his
;* name is but he used to do the cricket commentry on TV & radio but he died).
;*
;* He's a jolly old soul.
Code: Select all
; *************
; ** Barmaid **
; *************
; Pip can buy ale and some lunch at the pub.
;* The barmaid will be the stereotype busty wench from the old hammer films with just a
;* dash of Barbra Winsor.
;*
;* All the barmaid's innuendos will go straight over Pip's head as he is an innocent
;* sort of chap.
;*
;* If Pip should buy three Pints of ale in one visit to the Pub then in the software,
;* 's' characters in Pip's speech will be replaced by 'sh' (except where 'h' naturaly
;* follows 's').
;*
;* If Pip should drink too much then his speech will become slurred, therefore
;* All of Pip's dialogue should be recorded TWICE.
