The screenshot looks exciting, while my device probably just handles webgames than download-versions. Graphics, shadows, menu looks cool so far, while "middle mouse button"? Mine do have 2 buttons with a centered wheel, so probably that secret-menu or "+F" won't work in-game?
If there would be e.g. youtube-trailers or lets-play videos, I could let you know about closer feedback about my opinions, if you like?
