Still working towards 96 exits. Taking longer than I thought. Though I am trying to do it the suggested intended way and saving the switch palaces for last.
That's very much not the intended way but getting all exits except the switch palaces is a really neat challenge. There are some exits you have to be crafty about and some levels, especially some of the castles, become a lot harder. I've done these no-palace 100% runs twice and they're a great way to ramp up the difficulty.
Me, I just gotta clear out Valley of Bowser to get 96*, I didn't think I would bother but what can I say, I know the game well and I still love it.
