After beating it finally, here is my analysis. The game is good, however it has some serious flaws. a) aiming is difficult due to distance and bullet speed and firing rate, b) text is small and the font is weird, the "story" part often happens when there's action and i miss the dialog, c) it would make it a bit fairer if the capital ships had weakspots on them.
.....btw gaborthehun, i just beat hard mode w/o cheats. after lvl 7 i sold everything and just kept upgrading fighter jets.
basically, it's a terrible game, because it's pure chance to even be able to get to 10k points. you need a certain number of pills per unit time, if enough dont spawn, that means that you cannot keep playing. and it seems to be completely random how many pills spawn, so half the time you don't even have a chance of hitting 10k
