I'm pleasantly surprised that a tool I wrote 7 years ago still works on newer Tsurumiku games https://github.com/requiem90-throwaway/TsurumikuCGComposer
Their next game is probably going to have a different artstyle. Because as the game's Staff Room hinted, their original artist Sakura Romako is no longer with the company for unknown reasons. Some of the CGs in this game were made by a different group of people mimicking his style. Who knows whether he will return, or how much longer Tsurumiku itself can hold on...
