A very fun implementation on a simplistic idea.
I didn't mind crash issue, as far as reloading the page fixes it. Also, of course there will be bugs in a time-limited jam.
There is sounds or music, but we are investigating survelliance cam records which don't have a sound or music, maybe that was your intentional choice. But maybe a VHS tape player sound would be cool.
I really liked your approach on randomly created characters, but it would be better if there was more variants on faces, bodies, hair, etc. Because sometimes game can create exactly same characters. I was definitely sure about the look of the kiler, but surprise, there is a twin of him:
That was fun!
