I have a suggestion that we have sound and visual effects during the night in town of salem eg. gunshots and flashes signifying that member of the mafia has killed someone or maybe a explosion/incinerating sound every time an arsonist kills someone etc etc
I think (think, not know) that some visual effects are planned. However, they take the backseat in significance to bugs or major gameplay changes that will be implemented first. In my opinion, one of the things that makes this game so great is it's simplicity. Putting in too much would take that away.
Also, things like sound/light effects would all be triggered at the same time, at dawn. Because people change their minds, get role blocked, transported, etc, nothing is final until the last second of night. Having a ton of effects at the same time might be a bit overwhelming.
