The game was simple yet really engaging, the sound design was well executed, and I liked the way you interpreted this theme.
Feedback-wise, it was sometimes confusing to figure out which traits were acceptable and which ones weren't, and it would've been nice to have a little pop-up to inform the player when new instructions/parameters for entry would arrive. I never really figured out if there was any telltale sign of when I let an alien in, so I'd just have to guess and assume who it was when I saw the end-of-shift scores.
Nonetheless, really good job!
