I love this idea of new rules staking on each other, it really makes things challenging. Im personally just not a fan of the not all keys can be trusted and keys are rude now combination, because sometimes you think a key is just being rude and then you get killed, it makes things quite confusing. Also the tiles take a while to actual become useful, so maybe just dont have tiles be in the game until a rule involving them comes up, because I was confused for a while about what they were there for and tried a bunch of crap with them.
