Good concept and gameplay. User interface in non-gameplay parts was little bad, but it standed out only as rest of game was very well done. Worst thing in the game was that after getting hang of it, you can protect planet indefinitely, but you have no direction. Game could be little harder, or have some way to adjust(I would be interested of what would happen if planet could hold more energy, starts with more energy, but energy gained from flares would be decreased little bit).
+Art (supported other stuff well enough)
#Music( it was fine wasn't annoying, so, well done)
-No ending (if game would always end in defeat, that would also be fine)
What I would like to see:
I would like that player could zoom out, colonize other planets, and eventually build Dyson sphere around the star. Other would be that flares would start giving less and less energy, so that player would eventually fail.
Cool way to add to either would be if goal was to trey to build enough surplus energy that humanity could shift to other another star. In first suggestion, amount energy needed would bee so large, that player would need to have Dyson sphere. In latter it would be fight against time (amount required could even reset if you build more panels).
