Oh, you'll get a nice feedback when I can download the game

Doh! Forgot the download link!

I love the clean and minimalistic look.
In my opinion the diablo-style font doesn't fit, although it gives the game a little something, maybe try a clean sans-serif font with a certain personality.
Besides alle the small details should fit the clean settting e.g. the cursor

Keep up the good work!

Looks great! I love "simple" games with cool ideas!

Are you planning to release this also for money or is this the final version?

I've been hearing a lot about the font, so I'm going to change that and clean up the details (cursor, etc).

This is just the first three levels. I'll be spending the next six months working on the full version, which I'll sell.

After the Spyeart icon, i get an error: "Invalid pointer or handle in".

@Razoron: That is because you are running vista. Right click on the icon and click 'run program as administrator'.

Vista is not allowing the game to access the save_game.txt

Yeah, it works. Have to do this all time next. Fuck @ vista. Tommorow, my win7 will come to me .

Very cool, played the first 3 levels.

UI:

The selection to groups also works fine, but you
might add either number above the units (like a 1 if in
group 1)
or a field showing the list of currently selected units.

Attacking planes is a bit tricky. There sould be
some marker on the enemy units when howeving the mouse
over it, so the player can see its selected as attacktarget.

Tuning:
Overall the movement could be faster, and the combat longer
(lower damage or higher HP - so that the fights take longer)

I think the hope does not get used up yet, as ressource?

AI:

Also try to add a behaviour to the AI, that it flees
when low on HP, and retreats to some point near the base
to regenerate. This makes the AI harder to beat, by having
it behave "smarter"
The Harvesters should also retreat to the base when under attack, and return to harvesting after waiting
several seconds, when no other command comes.

Assemble the AI to attackgroups. So when one unit get attacked,
the others try to get close to the attacked unit and
then switch to normal attackmode.
Else the player can "pull out" single units from the group.

When the attackgroup lost too many units, it should return
to saver groud, and wait for more units before advancing again.

Should be enough to have one main attackgroup,
and a basedefence group.
The basedefence could be kept small,
as long as the player has not
approched too close to the AI base + the attackgroup has
several members.
Then the AI should assign all units to the basedefense group.
