Thanks for playing! I'm happy to know you enjoyed the art style.
The concept of the game is fairly simple: cut off the red threads of fate so that nobody will have love (reduce love of a level to 0).
It comes from Eastern Asian mythology where it's believed an "invisible" red string binds two lovers together. Eris is the Greek goddess of strife and discord. I came up with the idea that Eris had a relic of magical scissors, which are the only things capable of severing the red strings of fate -- and the protagonist somehow managed to steal it long ago :)
