What are the core gameplay and goals of the game?

The core gameplay revolves around a loop: 1. Obtain elements: Purchase or randomly generate basic elements from the base's conveyor belt. 2. Synthesize characters: Combine different elements on the crafting table to unlock new anime character recipes. 3. Earn currency: Place synthesized characters on the base's plots, and they will automatically generate in-game currency called "Yen." 4. Expand the base: Use the earned currency to buy more and more advanced elements and crafting tables to synthesize rarer, higher-income characters. The main goal of the game is to unlock all (currently over 340) anime characters, fill your character index, and build a powerful base capable of generating huge passive income.
