The demo is fun! I think some characters special moves need to have some restrictions in order to make them more consistent (Suisei's 214B has no height limit, so it's easy to get the timing wrong and not get a proper combo out of it) and I would say that there's too many 2As that whiff on crouchers than I would like, but the movement feels fun, pace is fast, and there's a lot of cool stuff you can do!

As a small note, in Suisei's command list, the Level 2 super input says that it needs to be done with the C button (632146C), when it actually needs to be done with the B button (632146B).
