This game is buggy as all hell and will sometimes get you stuck in inescapable geometry or even drop you off the map entirely. Since the game only saves at specific intervals, anything from your last save to the most recent glitch is lost. An instant death/zero health code would be useful for situations like this--as a joker probably makes the most sense.
I'm actually in busted off-mapville right now after collecting 28 of the 30 hidden secret items over the last four hours. I have a USB Gecko and hooks enabled, so hopefully I can still recover my progress if anyone feels like doing this. Thanks for any consideration.
