Character interface game in Linux

During this time, things were quite busy, and it was hard to take some time to find some game trainer. Here, it was ugly.

I tested it in Ubuntu 10.04 and it can run normally.

The Code uses the ncurses library. Compile the ncurses library, for example, CC-wall-O2-O mine. C-lncurses.

 

First, let's take a look at the page and try again with a dizzy look! :
