Ahhh, sorry to hear that the respawn was doing that to your eyes! I hadn't considered that. (Fun fact, I initially had a "dynamic" camera. It worked well, except that it gave me horrible motion sickness, haha) I've got an update planned eventually, maybe I'll add an option to disable the flying back to the portal, and instead snap back.
You're not the first to mention the hitboxes. I may adjust those during the update as well.
