It may be One Epic Knight, but it's several hundred different runs. From Simutronics, the creator of the inverted defense game Tiny Heroes, this tongue-in-cheek third person running game puts you in the golden greaves of a knight destined to run through a dangerous dungeon time and time again. The place is filled with dangerous spikey things, broken floors, tricky stairs, cuboid blobs, and much more. It's an absolute riot to play, so taking a jog or two through the halls is definitely a good idea.
With simple swipes of the screen, make your knight shift between the left, right and middle sections of the hallway, avoiding obstacles as neatly as you can. A trail of coins often tempts you into moving when it isn't absolutely necessary, but the goal is to go as far as you can without taking a hit. Items like swords and shields can be picked up along the way, allowing you to thwart enemies and breakable obstacles respectively, and you can also take daring leaps and slide below low-hanging dangers, just like any self-respecting adventurer should be able to do!
After you make a few runs in One Epic Knight, you'll have enough cash to purchase an upgrade or two. Buy potions to give you one-time bonuses like an extra life, or invest in permanent upgrades that allow items to grant you more uses per pickup. You can even save up for some crazy costumes, like a chicken suit. All of this can naturally be sped up using the in-app purchase system, but then you'd be killing half the fun of this never-too-serious game. Go on, stretch out those calves and go for a run. What's the worst that could happen (apart from a gruesome rock-induced death)?
