From November 15th the game will not be available on Steam in Germany anymore because it has no age rating

I just wanted to remind you of that. If anyone has contact to the responsible people for the game on Steam they could ping them or so.

There is some link for devs to get it through steam age rating:

They should have put in place an automatic adult rating if no rating instead of outright banning the games

it is blocked now and they don´t make money with it any longer, neither Steam nor the leftover rights holders.
