The only question I would have is why are you worried about playing Harem Heroes when you're in the Hentai capital of the world (afaik)? Why man, why!?!?!?

On a serious note, it sounds like you've exhausted all of your options already. =/

You might could've set up a TeamViewer free account on your home PC before you left and then logged into it from your mobile device. But I know that won't help you now, but might in the future. Sometimes hindsight is 20/20.
