You can rotate camera, actually =D

Oh my! It was not obvious at all, but I should've checked the settings in the options menu.

It turns out, you have to press mouse wheel in order to rotate the camera. But it is so inconvenient, so I changed it to the mouse's side button (thumb button =)

I hope I'll get along with this game well, 'cause it's pretty interesting, though there are so many things to learn =O It's a little bit overwhelming for now ^^
