PS:
This game was initially developed by Ayatsuji_san alone as a passion project during the difficult Covid-19 year of 2020, including programming, design, and art.
His good friend Berk joined in later on to make faster game completion possible. Additionally, a number of other people have supported the game with artwork and other fixes.

We hope that you love the game as much as we loved making it.
