Interesting game. I included it in my LibGDX Jam compilation video series, if you would like to take a look :)

Very nice RTS. It is hard to understand how the game works (Ai Test help me to understand), and some mechanics are weird (camera moving), but the game is fun and it becomes harder as time goes on, millions of enemies in everywhere, haha. I don't know what is the green objects that travels between planets.

The gameplay mechanisms and controls are unusual and surprising for a RTS. I was a little bit lost about what I have to do, but once I got it it was really fun!
Maybe you should think about giving more information at start for the player, like a small tutorial.

About the flag system, I feel it's very promising if it was more polished. For example, it didn't work so well to drag the flags (often considered just like a click), so I ended up not using this feature at all.

Had some trouble moving around the map. But pretty cool.

I appear to be to dumb for strategy games. It took me way to long to figure out what the mechanics are. Once i got it, the game was quite enjoyable. I agree with Broken Shotgun that the flag mechanics could be a bit better. I really loved the background music!

Interesting idea! Although I think standard RTS drag and drop selection of units would have worked better than placing flags. Also some sort of indicator that when aliens are on a planet that they are taking it over, I wasn't sure if I was doing it right until the creep appeared on the planet.
