So I bought the premium version

Regarding the true end:
The true ending was bittersweet. The dolls will always support and be there for Helen no matter what, and this fact made me sad and happy at the same time. Lastly, the animations, the CGs, and the amount of effort you put into the true ending is a masterpiece.
My fav is the wizard doll, hahah.
Okay, I will stop babbling about this.
