Hmm, the stuff in the Direct looks cool. The things in 3D World being exclusive is a tad disappointing, but it’s better that they’re there than not at all, as it still looks like they’ll make for plenty of new options.
Online Multiplayer looks pretty silly and fun, although I’ve seen it pointed out that it appears that online multiplayer is with randoms only (we don’t know for sure, but that seems to be the implication.) Furthermore, the local friends play doesn’t even appear to let you pick locally saved levels; the host needs to be connected to the internet in order to download random levels. I don’t really play online matches with friends much so this doesn’t affect me personally as much, but I can definitely see a lot of people being disappointed by it and it’ll prevent a lot of really fun scenarios from happening.
Nighttime gimmicks are cool and, again, it’s better that they exist than not, but I think they should’ve been implemented as “level modifications” or something that are displayed to the player on level load, so that they can be mixed and matched with any theme.
