Its a simple escape game. There is a hint function, so even beginners can enjoy it. There are many scenes that can be entered based on clues, but remembering without notes will lighten your brain training! (There is no memo or photo function) There is only one ending pattern, and you can play for free until the end. I hope it helps to change your mood.This work is based on the old flash escape games "Heart" and "Christmas Tree View Waiting Room" (both produced in 2015 and not open to the public).
