Koules is a fast action arcade-style game for X. This version
works  in fine (up to 900x620) resolution with cool  256 color
graphics, multiplayer mode up to 5 players, full sound and, of
course, network  support. Koules is an original  idea. First
version of Koules was developed from scratch by Jan Hubicka in
July 1995.
