I've got one awesome scene prepared for later on in Time Gate, where a character gets attacked by a monster, and their hearing is knocked out from the shock, and everything from that point on is the sight of his friends helping him out, screaming in the background, but you can't actually see what they're saying, so the speech bubbles are empty, because he can't hear it. It's a neat scene that I'm hoping I'll be able to pull off through the visuals.
I think there are a lot of neat things you can pull off with the first person perspective, as long as you're careful with it, and it works for the situation. Just gotta think outside the box!
