Hi All
We have updated Yukie to deal with the issue of Save files being left in the English build.
Please note that in order for Steam to not delete everyone's save files until now, the latest build now contains the chapter 1 save file, but your save data will be preserved as is.
For those who still have the debug save files, please delete or overwrite them. Sorry for inconvenience.
We have also enabled cloud saves, so the game will save to cloud when you open and close the game.
Thank you for your understanding and we hope you keep enjoying the game.
