Hi, it's resolved, so the bug i encounter was because i didn't extract the file in japan codage, i recommend to make a mention to explain this problem, this is how i fix it :
MENTION
Open Win Rar
Go to Option, select Japan codage
Extract the file
Enjoy the game
To make it simple : the game was build in japan codage, variable, so when you extract it with alphabet language it won't work because it doesn't exist for this language, you need to extract it with the original language.
The creator said to me too that Chapter 3 will be released this year maybe middle of this year. The creator want to make unlimited content apparently after Chapter 3. I don't know what he meant by that. Maybe DLC ?
I hope i help you, else for the traduction, i recommend you to use MTools, it work perfectly for me. The traduction is good not perfect but still good/very good. It depends.
