Very entertaining! Keeps you engaged and thrilled till the very end:) Took about 25 minutes.
I did get stuck once, on the screen with the reflection in the mirror, after going to the door on the right, it show me a screen with roots and R, and then back to initial bedroom. But after repeating the same few times I was able to get out of that cycle. Maybe I did something wrong.
Anyway, it's very cool and atmospheric game!
