Hey,
It's me again.
So...I tried the full game, and...what did you actually add?
The game is composed by three stages/levels (unless i didn't discover anything new):

• The Main Lobby

• The Science Labs

• The Core
  The first level it's the DEMO level, the same thing (a little difference is that now you can actually choose the flashlight).
  The second level is nothing...there's nothing interesting inside, not any clue on what happened or why the AI went bad.
  The third level is less than nothing...you defeat the AI...no super battle, nothing hard or scary...nothing...
  At the just The End...
  I must say that I find myself very disappointed on the outcome of this highly potential game.
  I read that developing a game with Unreal Engine takes a lot of more time than Unity and I suppose that you got tired of the game and gave it an ending.
  I suppose that just because there wasn't anything added to the game, not one scare added and not any peace of story has been revealed.
  I'm not judging you as a creator, cause I love the way you make games (audio, controls and graphics), but sadly this didn't work out.
  I'll be waiting for your next game.
  This is just a constructive criticism and nothing will make me say that you can't program a game.
  So keep it up and maybe try to fix these things next time.
  Still thank you for making it!!

By the Way I made a Let's Play Video of it, so if you want to take a look here it is: https://www.youtube.com/watch?v=4Vr57tKWPr4
Every feedback or constructive criticism is highly appreciated.
Thanks for watching!!!
