I think the layout needs a slight improvement as it looks fairly basic. Also, the style is a little too much like Pandemic's for my taste. Aside from that, it's a great, original game :)
Well ... yes, it is.
Learning is copying (altough I should say imitate or mimic, because copying could be understood as holding "ctrl-c" and "ctrl-v" consecutively, which is not the way to learn).
Loved the game but level 17 is extremely frustrating on normal, as the motherships build rate is ridiculously high (I have completed all other levels on normal)
