It's a really good game. At first I found it too hard but after you work out the AI kinks you can beat the blue guy after a few tries ^^. I really would have liked an easier first level :)
Really a funny little puzzle game. Not too hard but I also didn't get most of the levels first try. I turned off the music during the first level because it got to repetitive. I guess you also had some other songs later on?
I like the game. But I found it a bit tedious to switch between the blob-alien and the zombie group. It would have been easier if the zombies would follow the alien and vice versa
