The idea is interesting, but there isn't much gameplay per say. But that is to be expected, it's more of a social mental game. When I pressed play again then I was taken to a new scene with new texts - it would be interesting if it had loaded the same scene(track it via cookie for example) which I just answered, so I could track the progress of the game later as well (I wouldn't be allowed to try again the killing, but just the ability to view the added messages and eventually see what the mimic was). Just my thoughts.
Also I'm not sure if my answer registered - some feedback in the submission form about it would have been nice.
Hope you had a good jam overall :)
