Sokoban
=======
This is a GEM version of the classic puzzle game.
When started, the program displays a list of levels. Double click on the
level row to open that level. Move your character (a circle with a cross)
using the cursor keys, to guide the boxes onto the goals. The game has
unlimited undo: press 'u' or 'Undo' to move back one step. Press 'r' to
reset the level. A count is kept of your moves and pushes, and your best
scores are maintained on the level list. The display size can be adjusted
through the 'Scale' menu. Press 'Help' to view a summary of the key controls.
New levels can be loaded from a text file using the 'Game/Open Levels' menu.
See the file TUTORIAL.TXT for a description of the level format (which is
used by many level authors), and some examples, in case you want to try
writing your own levels. The game contains the original 50 levels of
Thinking Rabbit built in: these levels can be retrieved using the
'Game/Classic Levels' menu.
High scores are automatically maintained in a text file on disk. Selecting
'Game/Show statistics' opens a list showing how much of each set of levels
you have completed.
The implementation is pure GEM and should run on all Atari machines, TOS 1.04
and higher. If your display has less than 16 colours, Sokoban will switch
to a monochrome output. The program has been tested on a Firebee running
MINT+XaAES and, through Hatari, emulated Atari ST and Falcon machines.
Installation
------------
Simply copy SOKOBAN.RSC and one of:
- SOKOBAN.PRG for the Firebee (a Coldfire build)
- SOKO_ST.PRG for the ST/STe (a 68000 build)
- SOKO_FAL.PRG for the Falcon (a 68000 build with TOS 4 features enabled)
to a convenient location, and run the PRG.
If updating an older version, retain the file "scores.txt"
to preserve your previous scores.
