Regarding the SNES version, I went into it thinking the physics were gonna be worse like everyone else says but...no? I have to literally squint to KIND OF notice most differences. I still think this is a great way to play it, and has a good argument for being the definitive SMB1 experience with all the updated visuals. Even though this game in particular doesn't really need it imo, it is cool to have a save feature and the ability to return to any world you desire after beating them.
