I jump on the opponent and it is just upside down. You can't defeat the opponents who are still simple. I notice. Is there something wrong or how does it work that I defeat the opponents? Even if you hit them three times in a row, you just push them away.

Which opponents (cooper, mushrooms, etc.)?

Fe

I do not know how to call them. But are usually defeated with a jump

Ta

How do they look?

Fe

Brown and small

Ta

Fe

And why can't I defeat them?

Ta

Bounded on it?

Fe

Yes, I jumped on it

Ta

It's a bug!
