Bad
Nothing new on this game.
Really dull and short game, and the "profound message" he try to deliver its more than done, and the between levels dialogues show that "ad nauseam" ( :P).
Sure, is based on a classic, that i used to play and loved, but only to flip sides - we now are the atacker - its a poor atempt, and this trend of "make a game like in the eighties (pixels: woot!)" fails here, because the game only seems an inverted (and worse) copy of "Space Defender".
