The second liz model in the library made me laugh, I'll admit. User Arinura seems to have most of the glitches in this version mapped out, so I'll be answering "How To XYZ" questions in my replies. If you're gonna ask "How do I get past the bats?" the answer is savescumming. You need at least 1 life to spare when you get to the end of the room so you can just die to a bat and get transported back. Otherwise, ask away.
