Thanks. As far as the theme goes, the game is inspired by games like Werewolf, Mafia, Secret Hitler, and most blatantly, "Are You a Robot?" by Looney Labs.
The other feedback is great. I agree that replicant scanning should differ from detective scanning and perhaps have a penalty.
I also thought of having a "citizen" role or a "saboteur" role but ran out of time to implement it. I had the thought that citizens would have to pick up and drop off packages and avoid being killed by replicants. Saboteurs would act like citizens but be able to help the replicants against detectives.
Having some kind of other game aspects for players to be doing would be great, same with having better AI for the non-human bot players.
Thanks for playing and the feedback! At some point I hope to make a version 2.0
