Heroes
The playable heroes of One Step From Eden are intrepid warriors who want to reach Eden. All of them are also bosses, and become playable characters once you manage to defeat them from Tier 3 (World 4 in Normal Mode) and onwards (except for the starting character Saffron, and the Shopkeeper who unlocks when defeated at any time).
Each character has their own unique kits which can completely alter their playstyle.
