Ah, okay. I mistook it as a bug, I didn't realize that it was something partially implemented. I missed the camera entirely as well.
Sometime things that shouldn't work, do.
In terms of balance, two things stuck out to me. I was able to win easily using just the blue character and the pink character; the enemies were very weak and there weren't many of them. The charge attack was also very difficult to use effectively. I think these are probably issues related to the limited scope of this demo but maybe some tweaking could be done.
