Only One is an exciting hack and slash game that takes the player through an epic arena style sword fighting adventure. Developed by Ernest Szoka, this game is available for iPhone users and has over 1 million downloads worldwide. The game is designed to challenge the player to become the 'Only One' left standing on the ancient pillar of sacrifice.

The game has awesome retro pixel art graphics and music that sets the right tone for the game. The physics-based sword combat with parry and shield mechanics is engaging and keeps the player on their toes. One can upgrade their character over time with better stats and really cool abilities like push, freeze, bubble, inferno, whirlwind, and dart. The game has 100 levels of soldiers, slimes, archers, wizards, loot gnomes, berserkers, skeletons, bats, golems, and mini-bosses. Players can choose and play as multiple character classes.

The ladder-based leveling with checkpoints every 10 levels, score resets each time you die, and Game Center leaderboards make it an exciting challenge to become the 'Only One.' The game also has a floating virtual joystick, and endless battle mode. The in-app purchase of "Ultimate Power" unlocks the full game experience.
