Seriously, inputting smash attacks is a big problem if you play with tilt stick, which a lot of people do. Maybe it's just my controller, but I have an incredibly hard time inputting smash attacks. Please add an option to make it more/less sensitive and add a button that allows you to hold it and charge a smash attack, like Rivals of Aether. I find myself often D-Attacking attacking instead of F-Smashing. Thank you!
Another quick thing - maybe add a short-hop button and allow you to short-hop by tapping 2 jump buttons. There is just a lotta friction in the controls IMO
