Loved the alien's design, them lighting up in the dark like that adds a nice touch. I think the beginning room might be a little too dark, it was a bit confusing figuring out the first moments of the game because I got lost in the tiny room.
Overall I think this is a solid entry, there's a lot of tension with the aliens which might get lost after a bit once the player figures out they can outrun them, but that first screech in the dark and lighting them up always brings up a good spook.
Great job!
