I think it's weird that the bros attacks were turned into items. It doesn't change anything since they constantly give you more of them. If anything, it just made those attacks easier to spam since you don't need BP to do them anymore.

The game overall is fine. Even the worst Mario and Luigi game is still pretty damn good. (Honestly shows how great the entire series is.)

Also, my save file corrupted after I beat the final boss. I like to think the Shroobs got so pissed after I killed their princess, they decided to just delete my entire save file.
