Pros and cons are down below) Check out my vid here (likes and subs are highly appreciated, the game is the 2d there)):
Advantages:
The concept is very cool! I really enjoyed being at the same time in the game and in the game inside the game. It's cool that you could see how your actions affect both worlds and how the player is walking on the monitor when you are away from the computer. I t was something new and I enjoyed it a lot!
Disadvantages:
I guess it would be cooler if there would be an option to change the outcome and to save the player. Also, I would prefer if the creepy sounds would mean something more instead of just being creepy ambiance cues. When you hear someone walking around it would be really cool if that would be an actual thing. Also, I was expecting the door to give me a spook, I think it was such a good opportunity!
Overall:
I would rate this game 4 meta demons / 5. Enjoyed playing it a lot but I still believe that it could be scarier. The concept was very cool and original tho)
Hope my feedback was useful!
