To build:

    make

There is an alternate version which has controls that will make much more sense to those familiar with vi. See Alternate code below.

To use:

    ./prog

Try:

    # Make your terminal as large as possible, possibly reduce your font size
    # then...
    ./prog

Alternate code:

This version has the difference of moving forwards, left, backwards and right, where instead of w, a, s and d, you can use k, h, j and l.

Alternate build:

    make alt
    ```


### Alternate use:

``` <!---sh-->
    # Make your terminal as large as possible, possibly reduce your font size
    # then...
    ./prog.alt

..and maybe curse less than you might otherwise, but still probably curse (see below) :-)

Judges' remarks:

This game does not use curses, but you may end up cursing.

The code is made more difficult to read using an innovative, right justified, reverse indentation style.

Author's remarks:

Controls

• Movement: w (forwards), a (left), s (backwards), d (right)
• Fire: space
• Quit: q
• Pause: p, then use any other key to resume

       /\
      //\\
     /    \
    /______\
      /\/\

Compile and run

Linux

    cc -std=c99 -O3 prog.c -o prog
    ./prog

Windows

The only way I found to make it work is to use MSYS2. When using the MSYS2 shell you can install gcc via pacman.

    cc -std=c99 -O3 prog.c -o prog
    ./prog.exe

High score

Score will be shown in the top left corner. My best was 156. If you beat that I'll send you the image of a very expensive chocolate.
