About the Game

If you have ever wanted a game that works just as hard as you do, even when you are doing nothing at all, Point-Earning Fermentation! Susumu-kun delivers exactly that. Built around the cheerful world of fermented foods, this idle clicker from SHOGUN STUDIOS puts you in the company of Susumu-kun, a boy with a deep passion for pickles and probiotic cuisine. Your role is to guide him through the fermentation of various traditional dishes from around the world, collecting points and resources along the way.
The core loop is straightforward and satisfying. You initiate a fermentation session, and a countdown timer begins ticking down. Tiny yeast spirits appear on screen to rally around Susumu-kun as he works, giving the game a lively, animated feel despite its relaxed pace. Once the timer hits zero, fermentation wraps up and you receive two things: in-game points and yeast tokens used for gacha spins. The rarity of the fermented item you produced, represented by a star rating, determines how many yeast tokens you take home from each batch. Higher rarity items like premium kimchi or specialty natto variants yield more tokens, so there is a real incentive to keep fermenting and chase better results.
For players who prefer an active approach, several tools help speed up the process:
Fermentation Acceleration Button: Each tap removes one second from the remaining timer.
Auto-Tap Feature: Automatically presses the acceleration button at set intervals so you do not have to.
Tap x2 Mode: Temporarily doubles the time reduction per tap for a short burst, perfect for burning through a timer when you have a free moment.
For those who prefer to step away entirely, the game continues working in the background. The fermentation timer counts down even after you close the app, meaning you can check back hours later and collect completed batches without having played at all. This makes it an ideal game to run alongside your daily routine.
The gacha system adds an element of surprise to each session. Free gacha spins use the yeast tokens you collect, and each spin carries the chance to earn additional in-game points. It is a low-pressure reward mechanic that rewards consistent play over time without requiring any spending.
Daily missions give the experience a bit more structure. Tasks such as launching the app, completing fermentation runs, or reaching specific tap counts all come with point rewards attached. Clearing these missions regularly accelerates your point accumulation and helps you reach redemption thresholds faster.
Speaking of redemption, the point exchange system is one of the more versatile offered in this category of games. Accumulated in-game points can be converted into a range of real-world gift options:
Amazon Gift Card
Google Play Gift Code
Rakuten Points Gift Code
WAON POINT e-Gift
nanaco Gift
au PAY Gift Card
PayPay Money Lite
d Points
V Points
Ponta Points Code
The breadth of choices means most players will find at least one option that fits how they already spend or save money digitally.
Point-Earning Fermentation! Susumu-kun suits a wide range of players. If you enjoy idle games that reward patience, casual clickers that you can pick up and put down freely, or simply want a low-effort way to accumulate points during your commute or downtime, this title fits neatly into that space. The fermented food theme gives it a distinctive personality that stands out from more generic clicker titles, and the combination of idle mechanics with optional active play means you can engage on your own terms at any time.
