I like the title screen, it looks authentic.
You made the Mario sprites, right? I thought you'd go with the small Mario sprite from SMB3.
I'm glad you took my suggestions with the Toad and Peach sprites, they look way better.
I wasn't expecting Wario, the Wario sprites look familiar.
I was expecting the small Luigi sprites from SMAS SMB3.
I looked through your hack, it looks like the only thing you gotta edit is the spirits when the characters die, it's been so long since I hacked this game.
Good stuff, I'll play through it some more after I do my chores.
