After absolutely HATING the first game (mostly due to it's thoroughly unlikable and horribly acted protagonist) I pretty much ignored the second game in the series. I'm glad I finally gave it a chance when it came to Steam though, as it felt like a VAST improvement.
A MUCH more likable protagonist, a better paced story which still manages to be mostly ambiguous as to whether there's anything supernatural going on or not, more logical puzzles...there's a lot here which is much improved over the first game. It's a good length too but the variety of locations with a minimum of backtracking helps keep it interesting.
The voice acting is still mostly terrible, but that's pretty much to be expected of adventure games of it's time. It also has possibly one of the most ridiculously abrupt cliffhanger endings I've seen (from what I gather it runs directly into the third and final game) but overall...yeah. I liked it.
