About ULTRA MUSHROOM

ULTRA MUSHROOM - about the game
Join the outdoor festival at the mountain's base and chase entrepreneurial dreams with a zero-cost mushroom stall. Take your pig Buta into the hills to hunt mushrooms, balancing knowledge and speed to snag rare ultra varieties without missing sales time. Hype festival crowds by syncing banter to music rhythms on chosen stages, sparking orders and unlocking customer stories or stall helpers. Upgrade your setup with earnings for slicker cooking and service. Meet quirky patrons like mosh-loving Mosh, juice-guzzling dancer Juice, and info-rich Dr. Mushroom amid rumors of pig enlightenment and a secret fourth day. This PC adventure suits players who enjoy gathering, rhythmic selling, and building festival connections.



Welcome to the outdoor festival "Ultra Mushroom" at the foot of the mountain.
There was once a man who made a billion yen in just three days by running a curry stall here.

Our protagonist, inspired by this news, comes to the festival with the ambition of making it big with a mushroom stall (with zero cost mushrooms!).

Note: The mushrooms in this game are delicious, wholesome, and full of vitality. They're also very healthy.

Gather Mushrooms in the Mountains
Search for mushrooms with your pig, Buta, in the hills behind the festival. Your zero-cost dream relies on your mushroom knowledge and dedication. There might be precious ultra mushrooms deep in the mountains, but going too far could make you late for the festival!

Sell Like Crazy at the Music Festival!
The key to success at your stall is to hype up the customers! Choose a stage, match the rhythm of the dope music, and keep the energy high with your banter. The more you excite the crowd, the more orders you'll get, bringing you closer to your big break.



Feed them ultra mushrooms, and they might even start sharing unheard stories in their excitement! Some customers might even help you run the stall if you become friends.

Invest your earnings into upgrading your stall, making cooking and customer service more high-tech.
