Note that saving up and buying a later upgrade does NOT save you money, and in fact buying a previous upgrade lowers the price of the later one, so the money you spend is the same. Thanks for doing that.
Hey, I got an idea. 2 game modes, Normal and Survival. Normal, you go and after each boss the game saves. After beating a huge final boss, you win the game, or you can keep going forever. Survival, just keep going, no save games.
First thing I saw when I clicked on the game was "Get more Karma!!!" ....... That was/is a very bad sign. It gets worse when everything depends on Karma, even if in real life you're a good person....... lol
Knowing how to play the game, after I started a new file (cuz i had to, don't ask), I know exactly what to do, and I'm not overwhelmed: SPAM ZE NOVA TURRETS!!!
I like Vader. He has the nuke, 3 types of turrets for a suitable base, landmines, a laser gun w/ infinite range and piercing, and a lightsaber that works excellently for killing bosses (red devils, gorillas, mechas). If you don't know who to use, use Vader.
@BebiBliss: Just wait in front of him. As soon as he shows you his hard violet abs, slash him. 3 hits should do it. He won't attack you unless you attack him while he's blocking.
