I managed to clear it though using debug mode!
I was a little concerned about the fact that I had to take all the extra items to clear the game, and the camera behavior which tends to cause a little 3D sickness.
But more than that, it was a very memorable game with many points I loved, such as the great feeling when using scissors, the stylishness of the conversational UI, which is on par with AAA titles, and the inorganic friends with rich personalities and expressions, MEOW!
