An interesting read from the developer of the game. It is a bit long. In short, they were bullied with false allegations and decided to just withdraw the game.
At this point, the game has been blocked in 3 countries—Australia, Canada, and the UK. We don't intend to fight the whole world, and specifically, we don't want to cause any problems for Steam and Valve. They do a great job and are incredibly helpful.
If after reading the above, you still believe that such a game should not have been created, then we sincerely apologize to you. At the same time, we would like you to be a bit more open to human fetishes that don't harm anyone, even though they may seem disgusting to you. This is still just a game, and although many people are trying to make it into something more, it remains and will continue to be a game.
We've made the decision to withdraw "No Mercy" from Steam.
Note, the thing about the fetishes that harm no one, refers to an explanation of kinky role play and is not meant as a call to be open about any fetishes depicted in the game as a real life activity.
After trying to argue with people here, I understand that decision. There is emotion involved and a lot of unsound arguments. Calling out those false arguments makes you a babbler or gets you blocked.
There are things out there we do not like, but we can't just ban fictional things, because someone does not like it and invents some untrue arguments why no one should see it. Giving it a 1 star, or rather no star and ignoring it, would be appropriate to voice your opinion about the game. And I think activists sould direct their zeal to real problems and not fight the easy target.
