I just tried playing Super Mario All Stars and it feels wierd as hell. You move differently than you do in Super Mario World.
You can't control yourself during jumps in the way you would expect. There's a greater sense of momentum, and it feels bad. You also slide when you land a jump at high speeds, meaning that you can land on a platform and slide right off. I don't like it.
It is now my intention to play Link to The Past.
Also, an anagram of "SpidersRMe" is "Prime Dress".
And, uh, that's it I guess. I just had to rant about the wacky physics in SMALLS. That's the new abbreviation of Super Mario All-Stars, remember it.
