Anyone know how to get it?

有时候从上面斜着踩到敌人，不仅不判定敌人受击、甚至我自己要倒扣血。同高度碰到也是一样的，现在只敢用冲撞攻击了

Listen, I would really like to unlock baby Clownpiece and Eternity Larva, I completed every mission of Cirno, Daiyousei, Luna, and Sunny. I played Cirno story many times even on perfect. What am I doing wrong? Is there a secret to these other fairies? And I play Sunny and Luna yet Star Sapphire has not unlocked herself... Eye'm so confused.....

请问本地多人联机方式一定要使用不同设备（比如键鼠和手柄）才能进行吗🤔我使用键盘按不出来p2p3，想要一个键盘就能联机😭毕竟这游戏所需的操作键位少，完全可以双人同一个键盘另外貌似键位不能绑定到鼠标，有点小遗憾...

On a new save, fron the character selection screen, I can't select any character (a little selection animation plays, but does nothing). The "Go Back" button does nothing too. This happens on both single and multiplayers mode.
