Glad you liked it.
The title sequence will be completely different in the main game (more anime based)- it's only just been started, so I had to use something else for the demo. Plus, I needed to work out where to put it (originally it was a lot later), but I felt it worked better at the current place.
I have merged the OVN games into one, and it worked well (as far as I know), but I don't intend to put the main story games into one. It takes a lot of time, and I've got two more episodes to finish as well, so it's not a priority. If I did, it would only be the side stories, and then only after everything had been finished.
The comedy is used mainly to keep the player blindsided about what's coming - there is a lot of violence later on, some of it pretty graphic too.
