I don't think the houses should match the players roles, but they would match the design of the exterior, meaning that cave and yeti lair would look totally different from the inside
Also, there could be a few simple animations ( basic, not to make game run slower ) when you are attacked / transported or something.
All together, it would make night more bearable for all the roles that cannot chat during the night and increase the playability. I can also imagine mafia chat look like a round table with them together in one of the houses. All suggestions are welcome, this could be a purchased thing ( unlock night theme for a role by paying 5000 gold or by winning 20 games with that role.
One who deceives will always find those who allow themselves to be deceived.
