i'm a SF/KOF guy and my 1st impression on touching SMASH is = no combo? 
thereafter just keep fail jump back to platform against CPU in World of Light when i saw youtube they can jump back even at the edge of the MAP. i only know UP+Special and 2x jump.

after watching few youtube Smash video for beginner, there's a lot of tech things inside aside from mash button especially dashing for me.

Gonna attend the SG Smash group gathering this weekend and see how i can learn more on Smash. its quite fun tbh especially with the character amount.

The stamina fight early in the game ?
I used Kirby, perfect shield bayonetta attacks and use bayonetta own power against her.

Took me a few tries as I was fighting with a useless level 1 spirit lol. Also, if it’s too hard, you can always try later when you’ve a better spirit.
