Dear mentors.
I rewrote Debian patches to support the content of the demo version of
the game. The engine now supports the content of the demo version of
the game. When the game starts, the engine determines the installed
game content, and if it finds content from the demo version,
it turns on the mode for using the demo version of the content.
This allows games to be tested by anyone who does not have a copy
of the original game. A demo version of the game can be obtained
from many places.The most convenient way is to download using the
wget from the WebArchive. To install content from the demo version
of the game, open a terminal and run the following commands:
sudo apt install p7zip
wget
