Game has been out for a while now. It was released I think February 25th on Mikocon. Mikocon is usually the sole releaser of all eroge other than girlcelly iiar so sometimes they monopolise a game or 2 which only they have and will only be available for their VIP members for 2-3 weeks sometimes over a month. But if girlcelly or any other individual releases the game then they release it right after lol. I think that's 1 of the source of their income for maintaining their site and keep on releasing eroge but they always release them sooner or later so it's fair enough. We just have to be patient.
