Can confirm that it is working in Australia... having said that this game is not very good compared to others... the girls lvl but the only way to get more HP is to feed other girls to your main ones and getting any extra girls at all is not an easy thing. Unlike other games where low level fodder is common they are hard to come by in this game and some of them do not even add to your HP but instead up your luck that is a nice stat but won't help you get through higher levels of content on its own.

I should also mention that your girls start with 1000-1500 hp or so and feeding other girls to them (other then the special training girl) only adds 10-20 hp per girl and you need to have 2k+ hp to do well as early as the lvl 4-5 area.
