Think of the directions on your control device as the numbers on a number pad.
2 would be crouch, 4 would have you walk back, 8 would result in a jump and so on. We will use this number notation for the majority of this wiki to explain moves.
Step - or
When you step in the direction your character is facing, you get a front-step. When you input it in the opposite direction, you get a back-step. Every character has a slightly different step. Some characters, such as Tamaki, have full dashes.
※ Only Hakuowlo, Tamaki, Morgan, Konomi and Multi can super jump. Multi has a slightly different super jump.
※ Only Touka, Tamaki and Konomi can short hop
※ Only Mogan and Manaka can double jump
In general, Weak attacks are faster, have less range, do low damage, and recover fairly quickly, whereas Strong attacks are slower, have more range, do high damage, and recover fairly slowly. Medium attacks are in the middle.
