The roguelike is a sub-genre of role-playing video games, characterized by randomization for replay ability (no two games are the same), permanent death, and turn-based movement. Most roguelikes feature ASCII graphics like the one implemented by Jeff Lait.
When I first saw this implementation of a Roguelike for inPulse I couldn’t help but wonder how the creator of this game conquered the one button challenge. Jeff cleverly used Morse code to gain control over the whole keyboard. While traditional roguelikes use vi-keys for movement (hjlk), these are awkward in Morse code so the developer opted to use shorter keys: mian, where m is left, i is down, a is up, and n is right.
What’s also pretty cool is that the game even has a little “menu” which you can access from the “ls” command again all through Morse code.
