Notice regarding the addition of Steam Achievements that cannot be unlocked

Aug 30, 2023

OU

"Between something and someone." U-chronia is a mysterious world constantly changing like a book whose pages are flipped out of order. You will wear the shoes of OU, the protagonist, to live through this game-shaped experience—without knowing what it really is.

Thank you for playing "OU". Due to the operation testing of an update currently under development, some Steam achievements that cannot be unlocked have been added. We apologize for any inconvenience this may cause.
