I don't like writing negative reviews, but this game is not in a sellable state and should not have made it through the QA process. Firstly, there are no options for keybindings. In fact, there are no options at all other than language selection. No volume controls, no graphics options, nothing. Secondly, the game is unplayable with dual monitors because the mouse cursor is not locked to one screen. So every time I click the mouse, the game minimizes. The quality is on par with something you would submit as a school assignment. I can say without exaggerating that this is the SINGLE WORST game for sale on GOG. Don't buy it even as a curiosity. Just stay away.
