Personnaly, I think that this a great concept that could have gone with a little bit more playtesting! I think the idea of spying on the other villagers is really cool and the wandering aliens add a little bit of tension and stress as you have to find the impostor. I also think the idea of hiding the outside while inside a house works great at rising tension (especially since I got jumpscared by one of the ghost while leaving one house).
However, I feel like my enjoyement depended on which character I played, I started with Betty which seems to simply not have enough time to do her task (I feel like the locations are random but that might be me). I then switched to John which has all of his tasks at the same location, making it a lot easier to track the other villagers. Maybe starting the day at 8am instead of 12 would make the game a lot easier (especially since some villagers start their schedule at 7am, which is a lot before 12).
I really think the concept has potential! So I hope you'll continue to push the idea and make a better experience!
