Played with one of the new teams, completely no idea what I'm doing, managed somehow to get to neutral stage 5 before biting it, getting hit at all now drains 5% power, so uh... that's sucks. I was only ever able to hit max power by using a power bomb. :'D
Still though, oh boy, this is going to take some time to mess around with. Hopefully all the upgrades get translated, so far most of the sub-events seem the same as before (although now due to the UI changes, they're displayed horizontally instead of vertically) so those I could just do on my own time, other than that, oh boy... this game.
EDIT: Also, seems like most upgrades now go all the way up to level 100, where there's smaller increases after level 15 up through 99, then a big one at 100 again. For example, Yabusame's upgrade (barrier max up) is 75% at level 15, then climbs up slowly to 112.5% at level 99, then leaps up to 150% at level 100. A full max-out for that, however, costs roughly 60m gallons, which is uh... a lot given how much you usually get in gameplay when you do well.
