Ok, so me and my buddies played it the last couple hours or so.
And its great.
But in particular, Bowser's super armor status is crippling to many characters, especially those that rely on many little hits to rack up damage, or those that just plain don't do much damage with most attacks...
Basically, whoever played bowser, unless miraculously spiked into the ground long enough to be warlock punched (ugh...) would win the match because of it, and only one of us is normally good as bowser.
Wolf has a wierd problem with his forward smash. Most easily noticable in stages like Lylat Cruise, in which if his smash hits just right, it does very little damage and sends opponents so far before the hitstun allows any action that they are basically dead. Strange enough, Wolf, if spamming the jump button, followed by side-b, airial (fair for quickest chance) then up-b can make it back, but no one else has stood a chance that we've seen. By the by, the dead character's current damage has nothing to do with this, as the attack is a 1hko if pulled off, even at 0% before it hits.
Peach really needs more buffs to some attacks, and I know turnips in particular weren't worked on, due to the hassle of actually editing them, but the only real changes I can see are:
Forward throw: slows down the attack and appears intangible during it, says "this is fun!" then slaps for decent knockback.
Forward smash: can choose weapon based on tilting while charging.
Has two floats, hold jump to string both together (start 2 in basically the same frame that 1 ends)
Side-b: definately the biggest change, can cancel into anything but another special... but requires the second jump to be used before floats can be used in it. (not really such a problem when the most of the time you use the second jump to better position yourself, but...)
Overall, the focus of peach seems to have shifted from Downsmash, Forward Smash, Turnips, and Fair toward Side-b...
My apologies if this isn't the place for it... I guess I'll also post this on the Brawl Minus Forums if those character topics are active...
