with the first impressions i had for the past half an hour:

- doing an uptilt into down air at ledge kills them instantly, at higher percentages it gets the "galaxy effect" (which means it kills no matter what DI)
- doing back air gives tons of momentum, doing it multiple times in the air gives you such fast speed being able to die by simply doing it twice, but easy to use for air mobility to kill people and recover from the far sides of the stages
- upsmash and side smash both have no range and feel weird to use because of it, the hitbox does not go over the whole animation
- down smash is really strong
- down special should deal damage going downwards in the air and do way more damage as atm is seems useless
- projectiles should inflict hitstun, feels very sandbert like atm
- side B in the air falls down with the same gravity which feels weird

atm they are really strong in some parts but really weak in others, will post more things below if i find any
