The partnership with Sekai Project also fell apart due to 'unprofessional behavior' on the part of Winged Cloud. Sakura Dungeon was the first game released by Winged Cloud after their split with MangaGamer and team up with Sekai Project.
It's the 10th game in the Sakura series and is one of the few games outright banned by name by Twitch. Sakura Dungeon is a dungeon-crawling VN with RPG elements developed and published by Winged Cloud in 2016.
