Only One is a retro-looking fantasy brawler that takes place entirely on a vertiginous cliff top. Little pixellated enemies—swordsmen, archers, and annoying wizards who shoot fireballs—spawn periodically, and it’s up to you to chase them around and either slice them to death or knock them off. A green virtual joystick appears wherever you plonk your left thumb, and an attack button sits on the right. The combat’s surprisingly well-realized, too, with satisfying sound effects and a smidgen of tactical depth.
As they die, these enemies drop goodies for you to pick up: heart refills and shield power-ups, but most importantly power tokens that you spend on the upgrades (extra heart capacity, for example, and special powers such as a Jedi-esque force push) that quickly become vital to your survival.
