About the demand for 'magnet' upgrades: A part of this game that makes it challenging is struggling to pick food up fast enough to keep the penguins alive. If you had a huge magnet, most of the challenge that this game offers goes out the window. I think the creator should leave the game mechanics as-is, save for the ridiculously dumb penguin a.i. running into walls. Aside from that, a decent time killer. 4/5.
Whoaaaaa.....I just realized that the Planes section of the Shop screen, the squares make an optical illusion where on the background paper stuff where it intersects, it looks like all the other intersections (other than the one you're looking at) are darkened but no matter how fast you look at the a different one, you can't see it as its only visible in your peripheral vision. If that makes any sense.....
@ mafiaelephant: the reason that your infection radius hits less people than wanted is because you're probably clicking either on or near a Special Agent or Hero (which can NOT be infected by the initial blast), thus all your shots simply getting blocked. Sucks, doesn't it?
