Great Map making! Great dialog. Great story. Great mission. Great use of space & some smart ideas. A 7 level game plus two net levels. It ain't that easy either. But then, problems appear on the last of the solo levels, "Mother Can't Save You Now". What a shame. This reviewer couldn't make it work, definitely design glitches; aliens don't die, stuck between a wall & a persistent alien . . . that sort of thing. Maybe you can make it work. Might be worth a try (ahhhh the challenge). It was fun while it lasted!
