Thanks!.
Yeah, that's the whole point. You need to be extra careful to have "less" enemies (kill them) because you will have "more" enemies (they will respawn twice).
The camera is intended to be zoomed like the SNES games. It has the same proportion as some games like Zelda A Link To the Past. But I see your point. Personally, I don't like to zoom it out more than that, but I get it.
Thanks a lot for your review!
