So found this upcoming game: https://steamhost.cn/app/1346780/Kebab_House/
It uses characters straight from Good Pizza, Great Pizza https://steamhost.cn/app/770810/Good_Pizza_Great_Pizza__Cooking_Simulator_Game/ right in the main picture for the game.
The screenshots for Kebab House are also characters from GPGP but with some slight color changes.

Proof (sorry, this is coming from a Youtube, but this is where one of the characters is in GPGP: time stamp at 9:59: https://youtu.be/WiSK8rqXslc?t=599 )
from GPGP: https://i.imgur.com/tgPzQWg.png
from store page of Kebab House: https://i.imgur.com/JaSw7eO.png (not sure how to get a bigger picture of it)

If you need more proof, I can grab it.
