way too hard, can't even get past 1st level.
Why can I upgrade the ships, but not the planets? I can only upgrade the planet shields?
i,good sir,like it.
The concept of this game is too hard for me to understand.
easy and fun
Too much of a struggle on each level, it would be nice if you didn't lose your upgrades after each level.
most addicting game ever
hard i couldnt get past lvl 1 >:(
