I mean who knew? Making the old Pac into first person game works surprisingly well and those ghosts genuinely are the most terrifying thing I've ever encountered in any game. They... just... creep... upon you.

That's pretty fun. Surprisingly, it's actually quite a bit easier than the original. It seems like you are actually somewhat faster than the ghosts, plus you can "cut corners", so to speak.
