Acolyte's Pledge

Publisher Blurb:

Acolyte's Pledge is a traditional-style roguelike. It's a turn-based dungeon crawl into the depths of a long-forgotten temple to discover what dwells beneath. Along the way, you'll have to face and survive a host of creatures, some hostile, some not.

You play as an acolyte, the lowest level of paladin, empowered by your deity with the strength to vanquish the unholy and restore peace to the world. At least, that's what you believed, when you took up your Oath.
