Just Kidding New Demo Update! - Dreamcast Only

Hey there! I guess I wanted to get some bugs out of the way and fix the horrible horrible tutorial audio. This is only for the Dreamcast version though as I haven't had time to redo all the audio for the PC version. I'll probably post a few more bug fixes when they arise, and I'll try to get a reworked PC audio version when its ready.

Fixes:

- Reworked Audio

- Lighting Adjustments

- Reworked Checkpoint system

- You die in the pit if you don't have a VMU inserted

-Minor graphical fixes
