Denmark's Children Exposed to Violence at Home is a group dedicated towards the prevention of domestic violence. It's a noble cause! Pity their latest "ad" — a flash game involving woman-slapping — lacks the same nobility.
We can see where they're coming from; something akin to "No Russian" for the domestic violence scene. Make you do something horrible to better confront the horror. But the execution? It's a flash game. Where you do nothing but smack a woman around. Comes across a little tasteless.
As such, it's hard to recommend "Hit the Bitch" over the genre's existing powerhouse.
