Rogess: chess with roguelike combat

Roguelike games (previously) are "a subgenre of role-playing video game characterized by a dungeon crawl through procedurally generated levels, turn-based gameplay, tile-based graphics, and permanent death of the player character" (Wikipedia).

Jonathan Lessard and Pippin Barr's Rogess is a mashup of roguelike combat and chess, for two players ("mediocre AI available" -Pippin Barr), built from HTML5 elements and playable on mobile devices. Barr calls it "Surprisingly fun and different to regular chess."
