Honest review:
Nice Stanley parable like game. It really fits the theme well.
Dialogue is excellent. I felt compelled to keep playing. But I think the tone is a little jarring, as the dialogue is more jovial, but the atmosphere and music are more straight horror.
I died when I guessed the wrong code out of the 3 choices. I don't think that's great, given that I had to start right from the beginning to continue! Even my rage game let's you continue mid-way!!
You could have just used left click for interaction rather than E.
Plays just fine in the browser, btw.
