I really liked the idea, but a few things stood out to me. The first is that the game takes quite a while to start getting interesting, for me it took around 30 weeks, and once the murders started happening, I wasn't sure I was playing the game the right way.
You did a great job on the simulation and the visuals, I thought they were really nice, and it's impressive that you made this on your own. I reached one of the endings and I thought it was great!
I also think you should invest more time in your game page, it's what's going to draw people into your game, so don't hide this gem from them!
