One Step From Eden is a roguelike action video game created by American independent developer Thomas Moon Kang, and published by Humble Bundle. It features grid-based movement and combat mechanics similar to Mega Man Battle Network series, alongside deck-building gameplay and choice-based story progression.

The navigation takes place on a map with branching paths leading to combat encounters, treasure chests, and shops. The combat in One Step From Eden takes place on a 4x4 grid, where player can move the character one square at a time, and, provided they have enough mana, attack using spells in their deck; these take on the form of various close and long range attacks, and some apply status effects or restore health. The enemy moves on a separate 4x4 grid, and their spells follow patterns the player needs to dodge in time. Some battles have special conditions, such as the presence of non-player characters to save or defeat.

Each completed encounter awards the player with experience points, and choice to add new spells to their deck. Every level up and some events lead to artifacts, items with positive and negative passive abilities. Falling in battle sends the player back to the start with all gained spells and artifacts lost, but progress in the completion bar remains, which eventually leads to unlocking new characters and spells for use in future attempts.

CoolHandMike beats the game as fast as possible in the seeded mode while reaching the Pacifist ending.
