Really interesting game! To be honest I'm not quite sure I'd dare playing it. At least I'd have to be in a concrete headspace to be able to stomach really getting into any of the roles. Really nice layout, too!

I also made a game about (attempted) murder. It's a bit less free-form and it does have some rules, including dice, but you might like it. If you want to check it out, it's called The poison of suspicion.
