The art is amazing, nobody can deny that, and the concept of everything happening on a loop is cool. The hint about door 3 was really cool to figure out.
That being said, I didn't really understand the story or what was going on. At some point it said: "You have the final clue" and I was like: "I have no idea what I'm supposed to understand here". I think it could have been a bit clearer. Also, I didn't fully like the way it controlled. It would have been better with full first person controls. Now it was kinda difficult to navigate, especially since on web, it sometimes starts dragging the entire game screen as if I was dragging an image.
That being said, this is a really intriguing game and I'd love to see it fully worked out at some point!
