ZOMG! I got 45k points, 3 platnium medals, 110% accuracy, a combo of 65, and guess what? IT DISCONECTS! It makes me sad. I think I would have had the impossible badge too. I think I'm going back to playing SUper Crazy Guitar Maniac Deluxe 2 now...But it was a good game. But the only buildings you really need are the Power Siphon, the EMP Wave Launcher, and the HQ. Time Slow is nice, but not much help. Flak never did anything for me. It wouldn't survive to the point where it would hit something. Upgrade EMP all the way, and its a beast! Upgrade power siphon all the way, and EMP is a MEGABEAST!
It just looks like a mutant zombie-type creature to me. And as for copyrights, I don't think you can copyright a nameless, logoless creature. Pikachu is a different story. Pikachu is copyrighted.
