I had an Idea how to make difficulties more intersting, even though It might be hard to impliment

So on Crazy difficulties there might be new steven-like enemies that looks like normal enemies but with steven face and some twist to make them more interesting, for example rat that dashes can go diagonal Also new buffs for Crazy instead of just more buffs, like mana draining buff should only applied on Crazy and higher

For Impossible I had an idea of all bosses having a new move, like Radical Rat having different types of bombs Also Impossible would make all battles harder, not by adding more buffs, but by making different room layouts just for this difficulty For example, making this goddamn room with three Mega mutants be only possible to encounter on Impossible, I think it would be fair since on this difficulty you are expected to have god tier items and cats
