Castle is a modernized rewrite of the "Castle Adventure" game from 1984.
The original Castle Adventure
The Castle Adventure was written by Kevin Bales who released it as shareware.
Unfortunately the BASIC source code of the Castle Adventure was never released.
The game works in full screen mode without graphics.
Instead of graphics the PC character set is used to simulate graphics.
There are no colors except black and white.
The man is moved through the castle using the cursor keys.
Like in text adventure games simple two word commands are also accepted.
The gameplay as explained in the Castle Adventure
You are trapped in a deserted Castle
and you must escape. It is rumored that
the castle is full of treasures. Can
you find them all?
Use the cursor keypad to move your man
around the rooms. To pick up a visible
item, just run into it. To pick up an
item not displayed on the screen, use
the command GET. To attack monsters
just run into them, but only if you
have a weapon. The computer accepts most
two word commands. There are 83 rooms &
13 treasures. To see the High Score ,
look at the wall in the courtyard.
