Is this too aggressive?

It's been about 6 days since we let them be together and they are playing back and forth quite a bit. Heard that you should let them play to learn their boundaries and that play aggression is normal in the beginning but sometimes the big cat Midna gets too aggressive with the kitten Bojji to the point where he screams. Sometimes she bites his skin which makes him yelp and other times he just gets scared so he yelps. I always separate them when it gets too rough and he screams like this. Besides this they snuggle closely alot as well and Midna licks him often but it sometimes turns out like in the video . I just can't tell if this is good or not😵‍💫
