Thanks so much! That makes me happy to read!
I JUST figured out why the character disappears-- it was my squash and stretch controller. It was saying, "I'm detecting a sudden extreme change in position, I'm gonna go ahead and stretch her out to infinite length and 0 width, that's what you want, right?"
Should be completely fixed now, and I'll look at tuning the camera jolting next-- if that would change your ranking, re-evaluation appreciated :) I imagine not being able to see the character would make the game a lot less fun!
