So you are asking where to find your game files?
If its correct you should have gotten an Email from Itchio.
So look in your spam folder if its not in your normal inbox.
The Email should have a link leading to all the files so you can download it.
Next time I would appreciate you to use English for a question.
I am also not using my native language to answer.
I hope you will find the email and if you have problems, please contact me.
