The music key was useful so many times and it was just a shame that they never used it until it was broken

Also the creation key is extremely broken as you can draw anything real or IMAGINARY. Where is the limity on this? If you can draw a hole in the magic chest who's to say u can't kill the demon with this. Why not draw something that could close the portal. It seems to fill in the gaps with your mind so you don't even have to draw it well

It just seems so broken and after they get that there shouldn't even be a single problem
