Yes, Sir Questionnaire has MFi controller support!
Sir Questionnaire on iOS does support controllers and is compatible with the MFI standard.
Sir Questionnaire is a turn-based hack'n'slash game, where you enter a dungeon full of loot, creatures and mystery.
Each room gives you two options to choose from, choose wisely and survive room after room, collecting loot which will help you defeat more and bigger monsters as you venture deeper into the dungeon! Take pictures of your various encounters and complete your codex with information on the various entities that roam the dungeon.
Take on Quests as you enter every game, ranging from easy to hard, with each quest type giving you a reward for your next game.
The harder the quest, the bigger the reward, so again: choose wisely! Learn monster weaknesses, alternate uses for the many items in the game, and uncover secret items and hidden area's in this procedurally generated adventure.
Sir Questionnaire supports MFi controllers.
