I haven't managed to play this game for a while due to my Wii U being out of commission due to a dangerous power supply, but I did manage up to the end past Exor. It's quite fun, from what I remember playing, and it is our only time we'll get to play as Toadstool in an RPG.
This is the spiritual predecessor of Paper Mario, after all, though I've never played PM64 or TTYD sadly.
