Yukionna-chan Checker will continue adding features based on user reviews!
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️Thank you for checking out Yukionna-chan Checker!This idle game includes features such as displaying temperature and animated Yukionna-chan, but other features (such as resizing, for example) have intentionally not been implemented yet.This is because features conceived by the developer might end up being intrusive or unnecessary for players.(In fact, we have also received feedback that the animations feel too prominent.)We believe that by implementing requests written in reviews, Yukionna-chan Checker can become an even better game!If you enjoy this game, please write in the reviews which features you would like to see added!Finally, for some reason, please take a look at an image of Yukionna-chan whose IQ has become unusually low (there’s no particular meaning behind it).Read full article on Community Announcements (Yamimiya)
