Um, those aren't bugs! Switching FOVs and hitting enemies with time stopped is a core mechanic. You're meant to use it to survive. I don't think the game is completable otherwise. It's a limited resource though - the shadow only can only take a few actions before control switches back, and the shadow can't stun or push back enemies.
As for the two names, you're asked for names of two different things - one for your character, and one for the person you seek.
Thanks for playing!
