Played about 9 hours of it and enjoyed it. I dropped it one day out of the blue, but that's because I have "video game ADD."
I should go back to it.
There are reports of it being a messed up port. I experienced some problems for myself. I had controller issues, keyboard issues and I still can't aim manually. Meaning, when you zoom in to aim with a slingshot or something, I can't... no key on my gamepad or keyboard will move the cursor, except for up and down when it feels like it. Made some parts of the game really hard.
Also, in one area of the game, time slows down inexplicably. That section took me 5 times longer than it should have because I had to get through it in slow motion. Luckily, it's an area you never have to return to.
Despite the bugs, I like it a lot. Because of the bugs, I'd recommend the console version. But for $3.75, go for it.
