About this game
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." 🏆 Mastery: From Practice to Perfection 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. 🛠️ 15 Skills, 15 Times the Joy 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. 💆 Pure Idle Experience 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.
