I was wandering if ther is a way for me to play the game
I am from germany and steam doas not offer hentai game so this game is not available on the site 

so is ther a oather way for me to get the game?

I don’t know any honest ways, but you can create an account whose region will be different from yours,You can also look for a person who agrees to gift you a game, or give you a steam activation code, or search on alternative sources like GOG.
