Stuff I see:
-Kirby's general playstyle has not really changed, but he's become a lot better at doing it. Sped up aerial movement, properties of attacks have been altered, and just a general speedup. Uair isn't as powerful anymore, but it apparently combos?
-DDD chaingrabs! And Waddle Dees come out really quick >_>
-Charizard gives pretty good pressure, while it looks like thay hadn't figured as much out for squirtle/Ivysaur
-Apparently Smashville is their stage of choice (who would have guessed?)
-There's some manner of quick movement going on with DDD a lot that doesn't look natural, or I may just be out of the loop. A quick short dash in either direction on land without changing the direction you're facing... sounds oddly familiar
