You CAN'T be serious! I was doing AMAZING damage and I get a frickin spyware popup. Gah! No, not from the game or this site. Something wrong with my computer, but I'm pissed so I had to rant. Great game.
The reason Suns attract more than Planets that are more massive is because of the way the size is made. You have a planet that weights twice as much as a sun, but its radius is also twice as big. Since gravitational force goes down like 1/(r^2), the planet ends up being weaker because you are further away from it than the star. Bad modeling on the developers part.
Great game, especially the addition of the hero unit and towers that help it, but WAY too hard. OKAY, maybe not "way", but still too hard. If heroes started out doing more damage it would be great.
Not enough upgrades. Even better would be to let you choose them. Your projectiles should be a different color so you know what do dodge and what's yours. Should be easier to find the boss, too.
