 plomlompom tries to build his own roguelike. Currently, it doesn't do
 much interesting, apart from managing some ncurses windows in a bizarre
 fashion. You can move around a player and meet a random number enemies;

+they will occasionally hit you on contact, but without consequence to
+you: The player has no hitpoints so far. Enemies have 5 hitpoints at
+start and disappear if their hitpoints reach 0. The map gets generated
 randomly, too. There is only one save file (named "savefile"), and it
 gets overwritten each new turn. To start over with a new world, delete
 it.
