Unlimited lives.
In Eyesteam's action-packed platformer Call of Sword, swords aren't actually swords. ... well, I mean, yeah, they are, you can totally do sword-y stuff with them, like stabbing and cutting a tin can in half on late night TV. But they're actually powerful symbols of leadership and alien technology that might be able to save a crumbling world, so when a young boy discovers one, it's sort of a big deal... not that other people are content to let him hold on to it. Use [WASD] or the [arrow] keys to move and jump, with [C] or [L] to attack, and press [S] or the down [arrow] to block.
