Hey,
I'll start with forum suggestions cuz there are not special section for this. That's 1st suggestion - make one.
I'll write in English though i'm Pole cuz I there are no language specified sections and no threads with rules (which language I could use and where) or at least I couldn't find any. That's 2nd suggestion - make one.
I almost gave up this thread and intention to help cuz your forum-registration system is really annoying. I completly understand you need anty-bot system, but use something like "How much is three plus five? Divide that by two and write answer" not what games your studio hasn't released yet. How am I supposed to know? That's first game I'm playin from your studio. I had to check forum for these - twice. Cities in England aren't best idea too. That's 3rd suggestion - change it. Or you'll lost a lot of community support.
And at last game. 1 error and 2 suggestions.
1. There is no scallin for game summary when you are playin in window mode 1024x768.
2. I would really appreciate descriptions for battle stations, kinetic shields etc. Even "press alt to see description" and "Battle stations gives better defense to your planet ble ble ble". Same thing with fleets. And same thing with planets, why I can build ship at one and not at others? I should know it 10 seconds I start my first game. I know most of it is shown in missions (which should be described as tutorial or at least info "Play it first!") but this is so important thing that should be accessible at any moment.
3. I don't know if you tried to make everything minimalist, but you really should change icons of fleets, they are way too similar to each other.
Hope this will help. If I see anything else and got any ideas I'll post them here.
EDIT: I think that thing with not scallin attachment size is obvious thing to change.
