Well, what I meant by tweaks was purely in the mechanics but now that I think about it all I can think of that's different is that the punching Lui can stun enemies without removing their powerups aside from just being able to punch bombs so nevermind I guess.

I think there was a mount that worked exactly the same as power gloves (carry bombs) except that the mount ate the bomb that's right in front of it and you can continue to manipulate everything else as normal while holding the bomb in its belly before spitting it out. Can't remember if it was from Super Bomberman 5 or not. Probably from Party Edition too since that's what I've played recently.
