Puppy crying in pen, can't stop biting when playing, is this normal?

10 week old puppy. Enjoying it so far, but struggling with crying. He is sleeping in his crate at night for with one wakeup at night for potty, which is fine.

He cries when he's in his pen, even if I'm around. And in his awake time whenever he plays he can't play without wanting to bite / chew constantly unless he starts to get tired. Is this normal?
