Monastery is a roguelike game that was written during a period of seven days. Like many other roguelikes, it uses a simple ASCII display to show what's going on in the gameworld. As the player, you control a monk (represented by '@') who has made a long journey across the mountains and has just reached the monastery where an evil grandmaster rules. Your task is to defeat him.
What sets this game apart from other roguelikes is its time system. Each turn, you and the computer-controlled opponent simultaneously choose an action to perform, without knowing each other's choice. Then both moves are carried out simultaneously. This means, for example, that if your opponent tries to hit you with one of his actions but you move away that turn, then his attack will miss. To win this game, you will need to guess what your opponents might do, and act accordingly.
The game's controls are very simple: use the numpad to walk in the eight cardinal directions, or push a letter next to an action on the left of the screen to use that action (which will usually require you to choose a direction). You can also use vi keys instead of the numpad. To wait for a turn, use '5' or '.'. To quit the game, use 'Q' (with shift).
