Really like the alien's design in this game! Seeing it get closer and closer does raise the tension but I think it would help if the alien got multiple possible path to take! Right now, it feels like we have to switch cameras for a very arbitrary reason instead of something more unique.

Very cool game otherwise, like the visuals! 

I think you have an interesting concept and the controls are solid.  I wish the power didn't run out so fast or there was an tiny indication of when he's gonna move.  I had to sit back and watch him slow walk after door 3 XD.  Great potential though.
