Cosen has announced simulation game Piyorun’s Observation Diary for Switch. It will launch via the Nintendo eShop in 2019. While language support has yet to be announced, Cosen has websites for the game in Japanese, English, French, and Chinese.
The publisher did not share further information. The copyright at the bottom of the page mentions “Narwhal.GT,” which is the studio behind the Chinese smartphone game HeroG (iOS, Android), which features the same creatures from the Piyorun’s Observation Diary artwork. That said, this could be a port of HeroG, or a new game entirely.
