It was taken down due to a debate of letting erotic games be open and playable. Since bank companies like VISA, PayPal etc have bigger power over some big website such as this one, they taken down some game that have 'erotic tags' as well as this one. It started around August and may have noticed some changes or absence of popular ones not there.
That's my knowledge of what I remember, you may have to look it up specifically if you want more information on what happen months ago.
Thanks to that organization that is against most of the 18+ games now many sites like this one and steam has deleted a lot of games because of this new laws. Now they can't obtain money from it as they used to, or they got banned because of the fear that said organization sue them for letting this kind of games be played to the public, even if they are adults. Some of them evaded this by eliminating some topics or themes that are taboo or went to other websites to sell their games.
