Very good puzzeler, with a sort of finese in the art, a not-so-formal aproach, and a decent hour to beat without walkthrough. 3/5. Considering the non-famous creator, though, its a 5/5.
Love the colonization appeal. Rejuvinate the graphings via a little more gloss, and get some decent improvements for the scheme and controling of buildings, and your good. Easy 3/5
Very nice, needs a little polish here and there. Add some storyline, fix grammer, and easily a 4/5. Improve controls and easily a 5/5, if not a little simplistic.
Decent. Needs some programming to make it a little more interactive. That, or go casual and add WASD keys for move, and W to shoot. I like what has been made so far. Kongratz!
