It's a really good entry, I love the take on the theme and the story behind it. The art is really cute! I like that there are multiple questions you can ask each person, so you can chose what fact you will most likely know about them. This helped me because there were a few among them I didn't know much about. The voice acting was a really nice addition!
I did wish the game was a bit shorter, it became a bit repetitieve after a while. Also you having to click multiple times between each person felt unnecessary, maybe you could just show the stats at the end of a shuttle? When you filled the shuttle, you would first see the shuttle stats and only after continuing whether the last person you added was an imposter. Also I ran out of time after 46 persons, I would have liked some sort of timer during the game to show me how much I had left. This would also help with the feel of urgency, I totally forgot about the mention of a time limit at the beginning of the game!
All these things are kind of minor though, I really enjoyed this game, well done!
