Woahhh just got round to playing this and it's awesome - very polished and some awesome graphics. The combat is great, and I'm sure with a few more tactical options it would become probably the best 4x combat. You should really think about putting this on steam - it's way better than a lot of 4x games out there.
I've made a list below of some feedback - some of it is quite nitpicking/overly-critical, so I apologise for that. Also, a lot of these are personal preference (and mainly UI based, as I haven't had time to play enough for balance):
-The first thing that struck me was the cursor angle. Somehow it's...off. I think it needs to be rotated to the left a tiny bit. Seriously, I know it's a tiny issue, but it feels really strange - for the first 5 minutes it felt like if you haven't calibrated a touch screen properly.
-Right clicking to move ships on the galaxy map is also a bit odd. I'd like to be able to click on a ship and then right click where I want it to go. Right clicking, then left clicking seems strange and took me a while to figure out.
-There could do with being a 'universal' build screen, where you can set build orders for all your planets. If there is one I haven't found it yet. I think it'd be great to have it instead of where the 'rotate' option is on the main screen. I don't think it's needed, and it'd be a useful thing to have there
-I got immediately attacked by pirates. Perhaps there could be a 'safe' year or something so you've got time to work out what everything does/get used to things.
-The research screen could do with being a little bit clearer somehow. Perhaps having research in a 'tree' style would be better, as in a list it becomes a bit tricky to know what's what somehow.
Really, great work and I can't wait to see how this develops!
