As development progressed, the concept and direction of the game evolved. Lily Bergamo was eventually reimagined into Let It Die, which retained some of the core themes but introduced a new gameplay style and setting. Let It Die was released as a free-to-play action game in 2016, marking a shift from the original vision of Lily Bergamo.

Lily Bergamo was set in the year 2026 and centered around a female protagonist named Tae Ioroi. The game was designed to blend Japanese and Western cultural elements and was described as a "super action game" with a growth mechanic that updated player data progressively.
