The controls are the arrows... right shift... and enter??? Who thought that was a good idea? A scheme like that gives you 2 options: 1 - play with two hands crowded over each other -- this is very uncomfortable. Try it now to see what I mean. 2 - play with one hand -- this doesn't give you a lot of, well, control. You can't use either action button while moving up, for instance.
Yes, you can change the key assignments, but why is this even the default in the first place?? I have never, in my entire life of gaming, seen a pc game with such an awkward and bizarre default layout.
