You please can make the game a little bit more simple? i only have 2 gb ram :(
You can play it with 4gb but until we optimise it, it will be a bit slow. Ram is pretty cheap these days.
You can play it in the 'fastest' mode with a lower resolution meanwhile. See options when game loads.
Example 1024 x 768 with 'Good' mode works reasonably well even without optimization.
