Debut during Christmas period roughly 3 and a half years back, Nekopara took the world by storm via its release on Steam, one of the first of its kind.
The doujin game (Complete with optional erotic contents via an R-18 patch which can be purchased outside Steam) features a successor of Live2D technology called E-mote, which really brings out the liveliness (And jiggle physics www) of the characters of the ADV AKA visual novel game.
There are currently 3 Nekopara games out in the wild: Vol. 0 (A free prequel), Vol. 1 and Vol. 2. A fourth one, Vol. 3, will be available later this month (Edit: Delayed to end of May, due to health issue suffered by Sayori-sensei… Get well soon!)!
Aside from that, a successfully kickstarted 1-hour long OVA (Proud to be one of the pledgers) will be available later this year as well, and will come with a mini OVA featuring the main Neko in their kitten years. =w=
From the Steam page:
Why, it’s a cat paradise! Kashou Minaduki, the son of a long line of Japanese confection makers moved out to open his own shop “La Soleil” as a patisserie.
But upon moving out, hidden amongst his things were two of the catgirls, Chocola and Vanilla, that the family had been raising. When he tried to send them back, they begged and pleaded until he gave in and now they’ve opened La Soleil together.
With two catgirls who really, REALLY love their master trying their very best and occasionally failing — a heartful comedy opens for business!
See the Sayori NEKO WORKs’ mascots Chocola and Vanilla like never before, moving, and in full voice on screen. And now with the E-mote System, the characters smoothly move on screen changing expression and poses in countless ways.
