How to Unlock Characters for One Step From Eden

How to Unlock Characters

To unlock a character in One Step from Eden you must beat them in the fourth world onwards as a boss. Once you reach the fourth world any character you beat at this point will become playable once your run is over. The only exception to this rule is the Shopkeeper, a helpful character that sells stuff, who you can defeat at any point during a run to unlock the ability to play as her. Keep in mind that the Shopkeeper is the most powerful enemy in the game and as such is not easy to defeat.
