Just tried it. Wow, it was pretty terrible...
Seriously, this is the worst PC port I've had the misfortune of playing since Resident Evil 4. And no, I'm not an elitist PC gamer with a high end rig that declares every port to be TERRIBLE. Most ports are ok. Hell, I think the Darksiders 2 port is perfectly decent - it lacks some advanced visual options, but the game looks good, run smooth and the M&K controls are perfectly reasonable.
But this... this is just sad. The M&K controls are borderline unworkable, the button prompts are still A/B/X/Y, the same prompt often requires different keyboard inputs (I'm guessing just to fuck with me) like "A" sometimes being "Q" and sometimes "Enter", the mouse speed seems to change randomly from slow to squirrel-on-coffee for no apparent reason, and so on and so forth.
At this point I whipped out my controller, since I figured it might solve my problems. Mind you, it's not a 360 controller, but I've used it on a bunch of games, from the aforementioned Resident Evil 4 all the way to the latest Assassin's Creed games. I plugged it in, and the buttons weren't correctly mapped. No matter, I thought - I'll just go remap what needs to be remapped.
Then I realized that it has no options for remapping the controller buttons. At all.
At this point I just quit the game. Maybe I'll try again in a month or two. Hopefully it will be brought to a workable state by the community. Please note I haven't done any bitching about the graphics or the resolution or other such crap. No, I don't really care about that. But the game lacks BASIC FUNCTIONALITY. And no, I'm not buying a new controller just so I can play one game...
