well, i'm not quite sure if it would help, op anon, but i do have some recollection on the details of this game
the sprites of the game are reminiscent of those from this publisher: https://www.pixiv.net/en/users/2887717 (but i may be mistaken)
additionally, i am certain the artist for the CGs is nikuman (肉名) on pixiv. https://www.pixiv.net/en/users/1339823

cheers, most likely it's of no use to you but that's all the information i can offer
