Download this app if: you're a fan of roguelike dungeon-crawlers.
Android game Cardinal Quest makes for a very likable roguelike — Roguelike dungeon crawlers may not be nearly as popular today as they once were, what with the often brutal challenge and permanent death system with very few extra lives, but every now and again a solid, indie roguelike will come out and remind everyone why they're awesome. Case in point,...
Guide a fighter, a wizard, or a thief deep into a hostile dungeon to wrest the town of Hallemot from the clutches of the tyrannical minotaur Asterion, in this streamlined roguelike. Engaging, thought-provoking gameplay that's different every time, but fast enough to take in bite-sized chunks.
Old school fun — There's a real retro feel to this dungeon crawler game, but it's pretty tough and requires some patience.
