one thing i didnt like in v3 were the bob bombs, they were to cheap :p lol
^This. Make him throw a Shell or something like SMBZ Luigi. Even a Shell is kinda powerful so idk lol. And MarioDK, I know this might be weird but I remember in one of your SMBZ Movesets, you had Mario Flash Blue and he would be able to turn Metal at the risk of losing 20% damage. I would add that as well to SMBZ V4 but it might be to much for people to handle xD I would love to see a All in one SMBZ moveset instead of the powerups being broken up into different movesets. So maybe the powerups could be Regular, Fire, Cape, Metal or even instead of metal have him use a star since he does do that as well. Wow I am full of idea's today xD
