xflappy - Flappy bird clone for X11

Written in C89 for pure Xlib (no frameworks). Just a side-project written in two days, so it was only tested on Gentoo Linux, but there is no reason why it shouldn't run on other UNIX-like systems. Very slow systems might require an adjustment of DELAY (see: config.h).

I know that the bird looks terrible. I can't draw any better sprites.

Compiling and installing:

• Ensure that Xlib headers are installed. On Gentoo, that is "x11-libs/libX11", on Debian, that is "libx11-dev", and so on.
• ./configure For an installation into the local user directory, adjust prefix: ./configure --prefix ~/.local See ./configure --help for other configuration options.
• make
• make install

Highscore is stored in a file ".xflappy-highscore" in the current user's home directory. To reset the highscore, simply delete that file.

Note that when the program says to press "any key" in a menu, this excludes some modifier keys such as Ctrl, Alt, or Shift. This is for avoiding that window manager commands like Alt+Tab start a new game.
