The first game released by RoRoKaii in 100 years. It carries a tiny fraction (roughly 1/999,999,999) of all the "if I ever made a game" ideas RoRoKaii has had over the past 2/12 years.
A simple, relaxing idle game centered around skills, leveling, and collecting. As the debut title from RoRoKaii Works, it is proudly labeled a "Return to Roots" project, boldly embracing the design philosophy of: "We finally figured it out."
In this game, we care about the "bond" you form with every single item.
Mastery System: Every item can be mastered. Obtain an item 100 times, and you achieve "Mastery" for it.
Experience Feedback: Mastery is more than just a title. It provides vital Mastery XP, allowing your professional proficiency to reach new heights.
A Collector’s Paradise: Every ore you mine and every fish you catch is more than just a consumable—they are the stepping stones on your path to perfection.
There are 15 trainable skills in total, covering everything from production to exploration.
Some skills will make you filthy rich.
Some skills will bring you world-renowned fame.
And some skills... honestly, I just added them because 15 felt like a nice, even number. But who knows? They might suddenly become useful one day.
Stress-Free Control: No complex combos, no patterns to memorize, and no pressure to find the "optimal route."
As You Wish: You only need to decide: "Right now, I want to make this number bigger." And then, it will truly, slowly, and steadily get bigger. It’s magical, isn't it?
Day & Night Companion: Built-in Light and Dark themes. Your eyes are safe, even during those late-night sessions.
To put it simply: This is exactly the kind of idle game you’ve been imagining.
