For those unaware, Hatoful Boyfriend is a largely typical Japanese dating sim, only in lieu of waifish teenagers, your prospective mates all happen to be pigeons. Common pigeons, tough pigeons, especially fancy pigeons - whatever sort of teenaged male archetype you'd typically be into is represented in pigeon form. This bizarre twist earned Hatoful Boyfriend a cult following, which eventually spawned an agreement to localize the game for English-language territories.
Publisher Devolver Digital has offered no explanation for the delay, beyond a note that the game "needs a just a little more TLC before it's ready to hatch." Once this issue is cleared up, Hatoful Boyfriend will be available for PC, Mac and Linux.
