For the memes? Making FPS-Man before FPS-Man was ever made.
Knowing the locations of all ghosts can be surprising or scary, so I'm suggesting that Invincibility be also activated if this category is ever run. Could avoid a LOT of surprise deaths.
Alternatively, there could be two PacManovich subcategories: invincibility and no invincibility (you know, for us masochists). I figure you might as well at least have the opportunity to do either if you want to.
Ehh, I think invincibility would be best in this case. If you're headed straight for a ghost, apart from jumping, you're basically screwed (since you can't turn around). Camera's also wonky in this mode, so it's not easy to tell where a ghost is.
Oh crap. Banquet Bash is going to be a treat.
EDIT: Banquet Bash is no problem. SCREW YOU PINKY!
Yeah, I found out after this post about that. It can't be done on mine carts though.
Rotational mazes will be fun.
