Rogue's Eye

Rogue's Eye is a roguelike in the style of old-school first-person dungeon crawlers such as Eye of the Beholder, Lands of Lore, Dungeon Hack and so on. It was originally built in 7 days for the 2014 7DRL Challenge (with some minor polish added afterwards).

A sequel (with considerably longer than a week spent on it) is currently in development.
