Seriously an amazing game!
I really loved the story and the gameplay was super fun on top of the monstrous noises mixed in with the music. the sounds and music really had me on edge the whole time and really took it over the top for me! I really loved the shadow girl that walked when I was in the maze too.
One comment I do have is I think that the time between when you start the game and the instructor starts talking is too long. I thought that I had to do something and almost had enough time to minimize the game and open the gamepage to look at controls before he started talking. Also the time between when you take the serum and the effects start to play is a tad bit too long i feel.
ill try to refrain from spoiling so ill be vague but I loved what happened when you finished the third maze it really caught me off guard!
overall I really loved this game amazing work :D
