Can someone please tell me what "Hetaoni" is?

((It is a fan-made game based off the Horror game Ao-Oni. The story focuses on escaping a mansion that is being terriorized par a monster. And yeah, I dont want to spoil the rest. Its very good, I recomend it.))

HetaOni is a fanmade game based off another game called AoOni! (Sorry, there's an answer similar to this...) toi can download the English version, but it's not completed yet... And I don't know where toi download it... toi can also watch the gameplay on Youtube! I recommend toi do! It's very interesting! Except it's most likely discontinued. *sulks in a aléatoire corner*
