A few more points:
1. Your website is quite slow - clearly you are gaining a huge number of customers. Please can you factor in the costs to upgrade your webserver/bandwidth to accomodate this extra interest.
2. I'm seeing a 'lot' of typos, both in the game, and in the news items on this site - it even beats news.bbc.co.uk who excel at making them. Going forward, could you please proof-read all content either after adding to the website, or to the game itself. It doesn't take long, and avoids the reader coming to a jarring stop when reading.
On the Tutorials screen, one entry has an explanation text beginning "And" which should be "An", and also had another typo in the same sentence.
3. When creating a new game, I am finding the general interface to be unusually cumbsersone:
a) The dropdowns require that you keep the mouse cursor positioned precisely within the verical bar - if you stray either above, below or to either side of it, the dropdown loses focus and you're left holding down the mouse button with nothing happening; please change the dropdowns to maintain their focus for the entire duration that the mouse button is held down, regardless of where you drag the mouse - as long as a change in vertical position is detected, then scroll the slider up or down. Otherwise, if you increase the game resolution higher and higher it becomes painful to use them (I'm only using 1280x1024, and it's already frustrating).

When playing similar strategy games out there, I like to 'remember' what the original game settings were so I feel I'm playing against a 'standard' set of game settings, and maybe only slightly tweak them every few games. However, on the New Game screen, when you browse through the modifiers (density of planets, number of habitable planets etc), there is no way to return them to the original settings if you can't remember them, except to quit and reload the game. Even leaving that screen and then re-choosing New Game doesn't reset them to their initial values. Please add a reset button, or better still, mark the 'defaults' in some way.
c) A small point, but I'll mention it again for consistancy. The game 'modifiers' allow you to scroll left and right - these should all follow the same pattern, i.e left is used to decrease/minimise and right increases/maximises. However, some follow one rule and the others do the opposite - the button selections just need reordering.
